Video encoding methods save motion vector fields locally in a buffer to predict the following frames, thus reducing the size of the error pattern that is needed to decode the frames. Besides, this so-called motion-compensated prediction further reduces noise by reducing the signal-to-noise-ratio (SNR), regardless of the bit rate. Prior art is a spatial approach that reduces edge artifacts from blo
Video encoding methods save motion vector fields locally in a buffer to predict the following frames, thus reducing the size of the error pattern that is needed to decode the frames. If several pixel blocks have identical motion vectors, it is sufficient to save only one of these pixel blocks. The presented method reduces the amount of data, by using a model with 8 parameters of a higher order.
Coding artifacts in video codecs can be reduced using several spatial in-loop filters that are part of the emerging video coding standard High Efficiency Video Coding (HEVC). According to this invention a method for processing the pixel value of at least one image pixel contained in a current frame of a video sequence is provided that constructs an individual motion trajectory comprising
