Abstract:

In this study a number of image coding methods were implemented and applied to aerial reconnaissance photos for relative ranking evaluations by experienced photo-analysts. These coding methods were of three broad types two-dimensional transform, one-dimensional hybrid, and spatial. The compression rates used were 1.6 and 0.5 bitspixel. The effects of channel errors at a .001 error rate were also simulated and evaluated.
