Video image data encoding / decoding

Abstract

The present invention relates to the encoding / decoding of a video image in which a DIMD mode of luma and chroma samples is obtained from a block of samples to be predicted by filtering samples from at least one template area. Said filtering uses filter windows centered on sample positions of the midline of said at least one template area, filtering samples in at least one template area with a shape. A WHOLE NUMBER OF POSITIONS IN THE MIDLINE OF SAID AT LEAST ONE TEMPLATE AREA IN WHICH THE FILTRATION WINDOWS ARE CENTERED IS LESS THAN A TOTAL WHOLE NUMBER OF SAMPLE POSITIONS IN THE MIDLINE OF SAID AT LEAST ONE TEMPLATE AREA.
