This directory contains grey-scale images used as examples in "Introduction 
to Data Compression" by K. Sayood, published by Morgan-Kaufmann Publishers.  
They are 8 bits per pixel grey level images stored in raster
scan order.  If you have a viewer that does not permit viewing of raw images,
you can use the convpgm program to convert the images to pgm format.  If
you are working on a PC with a VGA display you can use the "showimg" program
to display these images.  Various other programs for use with images can also 
be found in the programs subdirectory.
