Shape adaptive transform coding of image data |
摘要 |
<p>The circuit uses transformation coefficients correlated with orthonormal base functions for transformation coding of digital image signals. The image elements are obtained from the segment-adaptive two-dimensional orthonormal transformation arranged in blocks of variable size. The circuit has a separator (100) for the DC and AC components of the image elements. A transformer (200) for the AC components and a parallel scaling stage (300) for the DC components, followed by a multiplexer (400) are provided.</p> |
