Test images are described in Images

The easiest image display program to use is xv. To call xv, use the following command:

( echo P5; echo xsize ysize; echo maxgraylevel; cat filename ) | xv -

For example, to display the 512 x 512 byte/pixel image "test", use the line:

( echo P5; echo 512 512; echo 255; cat test ) | xv -

During this course we will also use:

MATLAB - a high-performance numeric computation and visualization software (Sun workstation, Macintosh, PC) and its Digital Image Processing toolbox. A short tutorial on MATLAB functions will be given in class.

NIH-Image - a public domain software for image processing

Hypermedia Image Processing Reference (HIPR) - a set of computer-based tutorial materials on a wide range of image processing operations: image arithmetic, point operations, geometric operations, image analysis, morphology, digital filters, feature detectors, image transforms, and image synthesis.
