<p>Device for coding still images by segmenting the images into homogeneous regions to which a specific label is attached and coding the contents and the contour of the said regions. The contour coding means of this device comprise a coding sub-assembly (30) itself comprising means (31, 32, 33) for detecting the contours of each region, means (34, 35, 36, 37) for detecting, on the contour of each region considered in succession, so-called control points of the said region, the means (38) for transforming into a straight-line segment the contour fragment joining two successive control points, on condition that at least one criterion of validity of the transformation is satisfied, and for coding the polygonal contour constituted by the succession of segments obtained. Application: systems for transmitting and/or storing still images. <IMAGE></p> |
