    摘要: The method realizes a motion compensated temporal filtering (MCTF), the temporal filtering being replaced by an intra mode coding to obtain at least one low (L) or high (H) frequency picture if the current picture has a level of correlation with a lower previous picture at a threshold, the low frequency pictures obtained (L) being thus scaled to be adapted, at the energy level, to the pictures obtained by motion compensated temporal filtering, and comprises, at the end of analysis:a selection of the pictures obtained by intra coding of a picture of a low decomposition level with the additional condition, for the high frequency pictures, that this picture is derived itself from an intra coding. a calibration of the picture selected by carrying out at least one reverse step of the scaling step. The applications relate to video compression with temporal prediction.

    摘要: The method implements an update step which is a selection among at least the following coding modes: a default coding mode which doesn't use the motion compensation for the calculation of the pixel if the pixel is not connected or which performs a low pass motion compensated temporal filtering of picture H of same level if the pixel is connected, an update_MV coding mode which performs a low pass motion compensated temporal filtering of picture H of same level according to a default motion vector calculated by taking into account motion vectors belonging to regions or pixels in the vicinity of the pixel to be calculated. Applications relate to video compression for transmission or storage of data.

    摘要: A method for adapting 3D video content to a display under different viewing conditions is disclosed. The method has the steps of: retrieving a stereoscopic image pair; obtaining a maximum disparity value for the stereoscopic image pair; determining a largest allowable shift for the stereoscopic image pair using the obtained maximum disparity value; calculating an actual shift for a left image and a right image of the stereoscopic image pair using the determined largest allowable shift; and shifting the left image and the right image in accordance with the calculated actual shift.
