Paper Abstract
"Cascade coding," a technique of double coding an image is introduced in
this paper. Blocks of the image are first transform-coded and the retained
coefficients of the transform are then quantized by a Block Truncation Coding
C BTC) algorithm for transmission or storage. Upon reception or recall, the
quantized transform coefficients are used in the inverse transform to
reconstruct the image. The new method combines the spatial correlation
characteristics of the transform methods with the ease of implementation of the
BTC. Illustrations presented here on sub-bit image coding, shows it to perform
consistently better than straight Cosine Transform (DCI') coding.
