Segment-oriented coding of textured images based on successive approximation
The paper reports a region-based coding scheme for segmented textured images. The proposed approach uses basic principles of transform image coding which are generalized for the case of arbitrarily shaped image segments. The texture inside each region is described by successive approximation through a set of shape independent basis functions while the image partition is coded employing generalized chain codes. In contrast to other approaches aimed at segment-oriented image coding, the proposed concept does not couple texture description and contour coding. The computational load is kept low, especially for the decoding process.<<ETX>>
