ADAPTIVE BLOCK TRANSFORM IMAGE CODING METHOD AND APPARATUS |
摘要 |
<p>In a method and apparatus for transmitting a digital image over a limited bandwidth communication channel, an image is block transformed to produce blocks of transform coefficients; the transform coefficients are quantized in accordance with a model of the visibility of quantization error in the presence of image detail; the quantized coefficients are encoded with a minimum redundancy code; and the coded, quantized transform coefficients are transmitted.</p> |
