An embodiment of the invention relates to a method for processing the pixel amplitude of at least one block image pixel contained in a video sequence, the method comprising the steps of: constructing an individual motion trajectory comprising motion-shifted versions of said block image pixel over a multiplicity of neighboring frames; and combining the pixel amplitudes of the motion-shifted versions of said block image pixel along the individual motion trajectory using a weighting function, to form a processed pixel amplitude of said image pixel.

The present invention relates inter alia to a method for processing an encoded video sequence, said method comprising the steps of: &#x2014;reconstructing the encoded video sequence and providing a plurality of neighboring pictures; &#x2014;transforming each of said neighboring pictures or at least a coherent region of each neighboring picture into the coordinate system of a reference picture based on a motion model, and thereby generating a picture stack comprising transformed pictures; &#x2014;combining the pixel amplitudes of corresponding pixels of said transformed pictures using a weighting function, to form a processed pixel amplitude for at least one image pixel of the reference picture; and &#x2014;generating a processed picture based on said at least one processed pixel amplitude of said image pixel.

Processing the pixel value of at least one image pixel contained in a current frame of a video sequence includes constructing an individual motion trajectory including motion-shifted versions of the at least one image pixel over a plurality of preceding and/or subsequent frames, and processing the pixel value based on the individual motion trajectory. Constructing the individual motion trajectory includes choosing the at least one image pixel of the current frame as a start pixel of the individual motion trajectory, and adding motion-shifted versions of the at least one image pixel of preceding and/or subsequent frames to the individual motion trajectory. For each of the plurality of preceding and/or subsequent frames, at least two motion-shifted versions of the at least one image pixel are determined, and one of the at least two motion-shifted versions of the at least one image pixel is selected and added to the individual motion trajectory.

Parametric Motion Vector Prediction (PMVP) methodologies and components and systems for performing those methodologies are provided to more effectively and efficiently encode video content that includes complex motion such as zoom or rotation. By substituting the PMVP for a collocated MVP used in HEVC in order to reduce the amount of bit rate increase required when including the PMVP analysis in the bit stream. Further, compression of the motion vectors is provided in a three stage approach based on transformation, quantization and difference coding.
