On the basis of the contourprediction a new adaptive predictor is proposed, whereby flat areas and contours of a picture are processed with different predictors.

A method of contourprediction is presented which is based on the path coherence and limited contour expand, it can be divided into two courses: global prediction and local modification.
Subjective tests show that the adaptive predictor based on contourprediction improves considerably the prediction of resolution charts in comparison with the other intraframe coding schemes.
