APPARATUS FOR FOLLOWING AND RECURRINGLY ESTIMATING THE LOCAL STATE OF IMAGE CONTOURS AND APPLICATION TO ADAPTIVE PREDICTION FOR DIFFERENTIAL ENCODING OF TELEVISION SIGNALS |
摘要 |
<p>A device for following and recursively estimating the local state of picture contours defined by lines of N points distributed in accordance with an orthogonal sampling structure, said points being defined by successive numerical samples. The invention also relates to a differential coded pulse modulation coder and a differential coded pulse modulation decoder.</p> |
