Image compression and restoration incorporating prior knowledge
Trevor J. Hall, Angela M. Darling, Michael A. Fiddy · Optics Letters · 1982
It is shown how to incorporate prior knowledge into the restoration of an image from a finite number of its expansion coefficients in some basis. The significant image enhancement obtained for simple prior knowledge suggests an application to image-transform coding. A computer simulation is presented that demonstrates that compression ratios greater than 13:1 are possible.
