Excerpt of article text...

Welcome to our first article on image processing techniques. First, we will take a quick look at the field of image processing. Then we will study three basic processing algorithms. Next, we will incorporate these algorithms into three Thread subclasses. Then we will try out these subclasses on a standard test image.

Image Processing, A Brief Survey

Image processing is a large group of algorithms that operate on data in a digitized image. Some enhance certain traits of the image; others measure parts of that image. Some transform the image into a different form; others filter out data from the image.

Many of these algorithms have been used in medical and scientific imaging. Many are also used for forensic and military work. And thanks to products such as Photoshop, the consumer public gets to use some of these algorithms on their personal photos.

All these algorithms can be categorized based on the mathematics they use. The following are some of the more common categories you will find.
