Abstract:
1. A motion estimation method for processing images intended to be inserted, between a preceding original image and a following original image, into a sequence of images, each of the images being divided into a plurality of pixel blocks, and a motion vector being associated with each of the pixel blocks of a processed image, the method comprising, for a current block of an image being processed, the steps of: selecting spatial motion vectors associated with pixel blocks of the image being processed and/or temporal motion vectors associated with determined pixel blocks of an already processed image; generating candidate motion vectors from the selected motion vectors; calculating, by a processing device, an error for each of the candidate motion vectors; determining a penalty for at least one subset of the candidate motion vectors; electing a motion vector from among the candidate motion vectors based on the error that is calculated and the penalty that is determined; and storing information associating the elected motion vector with the current pixel block, wherein the determining step comprises, for each candidate motion vector of the subset:
