摘要： The invention relates to a video coding method of exploiting the temporal redundancy between successive frames in a video sequence. A reference frame, called I-frame, is first approximated by a collection of geometric features, called atoms. The following predicted frames called, P-frames, are approximated by the geometric transformations of the geometric features (atoms) describing the previous frame. Preferably, the I-frame is approximated by a linear combination of N atoms (formula), selected in a redundant, structured library. They are indexed by a string of parameters representing the geometric transformations applied to the generating mother function g(x,y) and the cn are weighting coefficients.

摘要： The invention relates to a video coding method of exploiting the temporal redundancy between successive frames in a video sequence. A reference frame, called 1-frame, is first approximated by a collection of geometric features, called atoms. The following predicted frames called, P-frames, are approximated by the geometric transformations of the geometric features (atoms) describing the previous frame. Preferably, the I-frame is approximated by a linear combination of N atoms (formula), selected in a redundant, structured library. They are indexed by a string of parameters representing the geometric transformations applied to the generating mother function g(x,y) and the cn are weighting coefficients.

摘要： A method for temporal decomposition and reconstruction of an input video signal is disclosed. The method uses a prediction process and an update process in the framework of motion compensated temporal filtering (MCTF), the motion information used for the update process being derived from the motion information used for the prediction process, and the method employing a block based video codec composed of an encoder and a decoder, the decoder having a residual buffer. A residual picture signal is received, and in response to the signal being decoded in the decoder, the residual picture signal is clipped such that the residual picture signal is reduced in precision prior to storing it in the residual buffer, thereby allowing the codec to use a conventional picture buffer that stores a reconstructed picture.

摘要： The invention relates to a method of selecting among N “Spatial Video CODECs” where N is an integer number greater than 1, the optimum “Spatial Video CODEC” for a same input signal I. “Spatial Video CODEC” is understood as the combination of any transform of the input signal, followed by a quantization of the transform coefficients and a corresponding entropic coder. Firstly from all the N “Spatial Video CODECs” for the same input signal I and a same quality parameter Q, the rate R and the distortion measures D are obtained. Q is an integer value between 0 and 100, defined by any rate-distortion algorithm to provide a compression of the input sequence with constant rate or with constant distortion. Further an optimality criterion is calculated. The optimality criterion is defined as the minimization of the value Ln=f(Rn,Dn) calculated for all the n from 1 to N. n is the index of the “Spatial Video CODEC”, where f(Rn,Dn) is a function of Rn and Dn. The function f may be defined as as f(Rn,Dn)=Rn+1Dn, , 1 being the Lagrange multiplier that weights the relative influence of the rate R and of the distortion D.

摘要： A method for temporal decomposition and reconstruction of an input video signal is disclosed. The method can use a prediction process and an update process in the framework of motion compensated temporal filtering (MCTF), the method can employ a block based video codec having an encoder and a decoder. A residual picture signal and a low-pass picture signal are received, the low-pass picture signal having a lesser precision than that of the residual picture signal, and in response to the residual picture signal being decoded in the decoder, the residual picture signal is clipped and reduced in precision, such that the low-pass picture signal, a reconstructed picture, and the residual picture signal have equal precisions. An inverse MCTF process, using a lifting scheme, can be performed on the clipped residual signal.
