ABSTRACT:
In a multichannel encoding method for encoding digitized pictures, in particular digitized stereoscopic television pictures, the digitized pictures are processed in different channels comprising at least a movement estimation channel to provide digitized picture encoding data. A particular processing channel is chosen on the basis of this encoding data. In the movement estimation channel an input digitized picture is divided into blocks of pixels to provide a movement vector for each block and an error for each block pixel. For each block, a set of values is calculated relative to a block mean error, a block error standard deviation, a block error mean deviation and an amplitude of the block movement vector to choose the particular processing channel assigned to said block on the basis of the set of values.
