Apparatus for encoding/decoding an image signal having a still object |
摘要 |
<p>An encoding system effectively reduces the substantial amount of data for transmission by way of employing three encoding channels which perform a compression process for individually extracting and coding the contour of the approximated foreground region consisting of a still object, the boundary pixel values of the pixels located on the contour and the leveled-down/trimmed pixel data corresponding to the contour and the boundary pixel values. Further, a decoding system for use with the encoding system serves to effectively perform a decoding process for a coded image signal by using three decoding channels containing the decoding path for restoring pixel information including a set of reconstructed boundary pixel values and reconstructed contour information. <IMAGE></p> |
