摘要 |
<p>The invention refers to a method for coding a sequence of digital images (S), each image having the same image format and comprising a number of pixels with assigned pixel values, wherein motion parameters (MP) between first and second images (I1, 12) are determined, where based on said motion parameters (MP) a motion compensation (MC) is performed for coding the sequence of images (S), where said motion parameters (MP) are included in the coded sequence of images (CS). The motion parameters (MP) between a first image (I1) and a second image (12) comprise a scalar field ( p ) having scalar values for a plurality of image positions in the image format, wherein the scalar field ( p ) is determined such that gradient vectors (MV) derived from the scalar field ( p ) correspond to motion vectors for the motion compensation (MC).</p> |
