If you have been learning to do digital photo editing in Photoshop and have been going crazy trying to do precise object selection the following information is going to be music to your ears. Just about everything you do in Photoshop seems to involve selecting objects or people for purposes such as copying, color correction, special effects, and more. Have you ever wanted to cut an irregular shaped object out of the photo for use with another background? It can be difficult if not darned near impossible to perfectly select the object using your mouse and the selection tool.

Let me introduce you to the "grow" tool. The grow tool give you the ability to easily select an object with a photograph with almost perfection. What used to be an enormous source of frustration is now a breeze. In fact, the "grow" tool makes what was previously often considered impossible possible.

Here is how the grow tool works. Let's say you have an irregularly shaped object that you need to select for the purpose of extracting it from the original image for use in digital photo collage. Without the grow tool you would have to increase the size of the image and slow move your curser around the object until you had selected the entire object and even then your selection would probably be off quite a bit. Another option might be to use he magic wand tool but the grow tool works wonderfully for this purpose.

When you select an area within an object the grow tool makes the selection grow or expand to the areas adjacent that are similar in color. Using the grow tool you don't need to worry about selecting your object perfectly to the edge. Just select the best you can and let the grow tool expand your selection to the edge of the object.

Precise Photo Editing Is Made Easy With Photoshop's Grow Tool

Is there a call you want to make without the extra cost? With your computer in tow and an Internet connection, you can make calls over the Internet in the middle of everywhere, even in busy airports. What is VoIP technology? That's what this is all about.

Calls On the Go

Say goodbye to costly telephone bills. You can make a call from your computer when there are pressing business reports to make, even in a crowded airport or a cafe. Times have really changed and you have to know what is VoIP, or voice over Internet protocol, and how it gives you calling convenience.

If you're a frequent traveler, business or otherwise, you've spent the best part of your life waiting in airports, from small domestic airports to massive international ones. A call here and there is inevitable, especially if you have to give those last minute and often urgent instructions that seem to come out of nowhere.

Isn't it time that you should know what is VoIP technology and what's it all about? Of course, you'll need a chic Bluetooth headset and an IP server to get you going. Life spent in airports can be less of a headache if you can just connect to home and the office when there are pressing needs just before your flight is called.

In the boardroom, the VoIP is taking teleconferencing to another level. The big chief can call his minions and talk to them at the same time without racking up costly long distance calls. The meeting goes on with perfect attendance, even if two or three guys are away on official business or on vacation!

What You'll Need for VoIP

The VoIP process packages your voice into a digital signal which travels over the Internet superhighway. If you call the standard landline phone number, the signal is converted to the regular signal even before the phone rings.

You can make your calls from your computer using a VoIP phone or the traditional handset which you will have to connect to a specialized adapter. With this adapter, you can make calls anywhere, as long as Internet connection is available in the area.

Before you can fire away with a VoIP, you'll need to get a VoIP server. You have the option to avail of free teleconferencing quotes online. When requesting for a quote, you'll be required to answer a few questions, such as when and where you will be hosting your teleconference, the number of teleconferences a month you will be hosting, and the number of participants in the teleconferences.

You are also given the option to choose from "reservationless" and pre-scheduled conference types. For the pre-scheduled type, an operator will assist you and handle all the salient details. You can also request for additional services, like transcription and call recording. Knowing all these details will give you an idea exactly what is VoIP teleconferencing about. Furthermore, you'll also need Bluetooth headsets for your workforce on the go to get extreme coverage from your VoIP system.

So What is VoIP Doing in the Boardroom and Airport?

Your VoIP is working hard to ensure that you've got all your business calls and voice emails covered with less expense. You'll have the latest reports and updates without that extra painful cost.

What Is VoIP Technology Doing In The Boardroom And In The Airport?

Are you one of those people who would rather drive around town for hours than stop and ask for directions? If so, a Global positioning system, or GPS, could be the perfect tool for you.

A GPS is an operational navigational system that employs the use of navigational satellites. In other words, it tracks an individual's location or provides direction, all by using an existing satellite system. GPS units are also capable of providing real time reference on earth, or within its orbit.

The satellite navigation system was implemented and first used by the United States of America's Department of the Defense. Later, the system was adopted for use by other countries including Europe (Galileo) and Russia (GLONASS). In the United States, any US citizen may use the navigational system, free of charge.

The satellite navigational system is primarily divided into three segments:

* Space: As the name suggests, the space segment works from outer space. It operates through a GPS satellite constellation, located in an Intermediate Circular Orbit.

* Control: The control segment of a satellite navigational system is comprised entirely of control stations that are located on earth. These terrestrial control stations are scattered at locations around the world. These control the flight paths of the various GPS satellites, and synchronize the atomic clocks in the satellite. Ground stations also monitor the uploading of data through the satellite transmissions.

* User: The satellite navigational system is mainly made up of civilian and military GPS receivers.

A GPS is technically comprised of 24 satellites, the minimum number of satellites in a constellation. These satellites orbit around six orbital planes, twice in every twenty-four hour period. Each satellite carries an atomic clock, which continuously transmits precise time to the ground observatories located in the Earth. Additionally, the satellites send electronic messages to the earth. These messages may include data on precise time based upon the onboard satellite clocks, or information on their own orbital systems.

It's not necessary for the user to be equipped with the precise clock, however a good short term clock may be required in order to receive the satellite transmissions best used in determining the exact location on earth. Different satellites employ various sequencing modes, allowing the transmission of messages to be received by the user from satellites using similar frequencies. <

The primary GPS system was created to provide control over the military forces in the United States. This allowed for improved command capability, as well as the targeting and manipulation of missiles, smart bombs and other forms of ammunition. The satellites are also able to detect nuclear detonators.

Civilian users can also access the GPS system through their GPS receivers and GPS system software. Many cities in highly urbanized countries have improved the lives of their citizens where access is available to the free worldwide GPS Standard Positioning Service. The transportation sector has greatly benefited from the system, as many planes, ships and cars employ GPS systems for navigation. Hikers, glider pilots, mine truck drivers and everyday travelers enjoy access to the GPS system through low cost GPS receivers, ranging in price from $100 to $200. GPS receivers that are more precise are widely used by land surveyors for measuring land surface area, locating boundaries and surveying markers.

Time code generators also rely on the GPS system to acquire accurate time for precisely recording events in real time. Developers are also working on specially created GPS systems that will help visually impaired individuals.

Another, more trendy use of GPS receivers is the widely popular hobby of Geocaching. Children and adults use hand held GPS receivers to navigate designated sites and locate hidden objects. There are countless Geocaches hidden all over the world, with coordinates available on Geocaching websites.

The GPS system has brought both excitement and simplicity to the lives of countless people, all over the world. Despite the complexity of the system, anyone with a GPS receiver can use the service, free of charge. So now you'll have no excuse for getting lost.

GPS Systems

When documents containing bar code symbols are faxed, the quality of the bar code symbol will degrade. Documents scanned by fax machines in Standard Resolution are sampled with 204 horizontal dots per inch and 98 vertical dots per inch. Each sample point is then converted to either a white or black value (a process known as binarization). The binarization process converts straight lines of the bar code symbols into ragged lines changing the width of the bars and spaces. If a faxed document is itself resent out as a fax, further deterioration occurs. Each additional fax cycle continues to degrade the bar code. At some point, the symbol may no longer be able to be decoded by bar code decoding software.

The remainder of this article will discuss the issues that should be considered when selecting bar code symbologies and sizes to increase the likelihood of successful decodes after multiple fax cycles.

Linear (1D) Symbologies

Two popular 1D symbologies were examined: Code 128 and Code 39. Code 128 uses four bar and space widths to encode information, while Code 39 only uses two. Thirteen module sizes (smallest element) ranging from 12.5 mil to 32.5 mil of each symbol type, encoding ten numeric digits, were printed on a sheet. The sheet was sent through a fax at Standard Resolution for a total of ten cycles. This corresponds to a horizontal sample per module ranging from 2.6 to 6.6. The resulting 11 pages were then scanned on a flatbed scanner at 300 samples per inch and were presented to a bar code decode software toolkit. At 2.6 samples per module both bar code symbologies were only able to be successfully decoded for 3 faxes while the same codes with 6.6 samples per module were still readable after 10 faxes.

The larger samples per module (6 samples and greater) were able to successfully decode after 10 fax cycles. At 5.6 samples per module, the decode performance was no better than 4.6 pixels per module. This demonstrates that each fax cycle alters the bar code in a subtle way. Every fax cycle produces a unique version of the original bar code, and each alteration can make a symbol that did not read after a certain number of fax cycles read on the next one. However, if high read rates are desired after many fax cycles, then printing the bar code symbols at a minimum of 6 samples per module is recommended.

From the testing conducted, Code 128 slightly outperformed Code 39 after multiple faxes. Given the higher data density of Code 128 and the built in checksum, Code 128 appears to be a better choice between the two symbologies. The images below show the size advantage of Code 128 over Code 39, with both symbols encoding 10 numeric digits with the same module size. If the data to be encoded is purely numeric, the numeric compaction mode of Code 128 can be used to further increase data density.

There is a trade off to consider: the larger the module size of a linear code, the more horizontal room will be required to encode the same amount of information, but the larger modules sizes can improve read rate. One additional factor to consider is the bar code height. For this test, all the codes were ½ inch in height. Given that all vertical information in 1D bar codes is by definition redundant, if space allows, increasing the height of a bar code will typically provide better read rates after multiple fax cycles.

Matrix (2D) Symbologies

Matrix symbologies provide dramatically better information density because information is encoded in both horizontal and vertical directions. Given their size advantage over their linear counterparts, 2D symbols can be printed with much larger module sizes and still be comparable to linear symbols encoding the same information. For the 2D test, we printed various sizes of Data Matrix and Micro QR Codes. The Data Matrix was a 12 x 12 module square symbol. The Micro QR is a more space efficient version of a QR code that employs only one finder pattern and is limited to a number of smaller sizes. The symbols were encoded at a comparable level of error correction. The module sizes varied from 39 mil to 79 mil. Like the 1D test, we subjected the image to 10 fax cycles and then scanned the images. The images were scanned at 150 samples per inch given the large feature sizes of the test bar codes. The scanned images were then processed by the same bar code decoding toolkit.

At 8.7 samples per module the 2D bar codes were able to be read after 5 fax cycles and once 15 samples per module were reached the codes were readable up to 10 cylces.

The results were not as consistent as the 1D symbols. This is due to the fact that the distortion of the symbol during the increasing number of fax cycles affects data in both the data dimensions. However, we can draw the conclusion that symbols with larger size modules will decode more reliably after multiple fax cycles.

Summary

If documents containing bar code symbols are to be faxed multiple times, the bar code symbols must be printed with larger module sizes to be successfully decoded.

For linear symbologies, if a large number of fax cycles (greater than 5) is required, the number of samples per module should be at least 6. Code 128 performed well in our tests and has a higher data density than Code 39. Linears are a good choice for encoding small amounts of data.

For larger data requirements, 2D symbologies such as Data Matrix, provide good decode performance after faxing if larger module sizes are used. They provide the added benefit of reducing the amount of real estate required in the application document due to their superior data density.

The Effects Of Fax Transmission On Bar Code Decoding

Almost everyone can remember the day in school when they got to the science class and the teacher had the microscopes on the table. We all knew the fun that could be had looking at things up close and the things that we came up with to look at were almost infinite.

Telescopes were also a favorite in the classroom, yet not quite as much as viewing the world of scabs, hair or whatever gross object that a middle school child could find to view up close and personal.

Microscopes and telescopes have the interesting effect on pre-teens and the thought process that they can come up with to view with microscopes and telescopes is often times quite original.

Microscopes and telescopes are quite similar in that they are both utilized to view objects up close. The utilization of microscopes and telescopes dates back to the early 17th century and the similarity in the use of convex and concave mirror and lenses to make them have not changed much in the last few centuries. While these similarities in materials have not changed the utilization of technology has increased the abilities of microscopes and telescopes.

Microscopes and telescopes have evolved into computer versions that allow the user to manipulate the scopes and view the images on a computer. The computerization of microscopes and telescopes allows the user to manipulate the imaging process as well as the search process.

Differences in Microscopes and Telescopes

Beyond the obvious viewing material, looking at organic material under a microscope or the stellar skies with a telescope the microscope and telescopes differ in the manner in which they produce images to the user and the various types of microscopes and telescopes produce varying results that enable the user to view various images. While microscopes provide the user with a view of material in an easier manner than the telescope user, since telescope use takes patience to find various objects in the sky.

While many of us have fond memories of our first microscopes and the dream of our very own laboratory and although many of us are older we can still pass that passion on to our own children or grandchildren by introducing them to microscopes and telescopes. So when looking back at your childhood and remembering the times with your microscope or telescope take the time to share those memories with youth in your life.
