Paper Abstract

Distributed office systems employ the image exchange facilities such as image input/output, handling a softcopy, image filing service and so on. This paper presents a study of the segmented image exchange approach suit well for block based image coding and image processing schemes. From the result of the feasibility study, the segmented image formatting criterion provides a well-designed quantization-table set for DCT coding scheme. The 400 spi full-tone image coding simulation of the segmented adaptive quantization for DCT coding shows the better SNR and the perceptually better image quality than that of the conventional scheme. To select the quantization-table in the decoder, this scheme requires 3-bit header for every coded block. However, it enables another image processing features in a reconstructed image.
