20140064380 | FRAME BUFFER COMPRESSION FOR VIDEO PROCESSING DEVICES - For compressing a video signal, a local multiscale transform is applied to a frame of the video signal to obtain coefficient blocks. The coefficients of each block are distributed into a plurality of coefficient groups, and for at least one of the groups, a common exponent is determined for encoding the coefficients of the group, and respective mantissas are determined for quantizing the coefficients of the group in combination with the common exponent. Coding data including each exponent determined for a coefficient group and the mantissas quantizing the coefficients of the group in combination with this exponent are stored in an external frame buffer. | 03-06-2014 |
20140023149 | SPARSE GEOMETRY FOR SUPER RESOLUTION VIDEO PROCESSING - In a method of analyzing an input video sequence, pixels of synthesized images of an output video sequence are associated with respective directions of regularity belonging to a predefined set of directions. A first subset of candidate directions is determined from the predefined set of directions for a region of a first image of the output sequence. For a corresponding region of a second synthesized image of the output sequence following the first image, a second subset of candidate directions is determined from the predefined set of directions, based on images of the input sequence and the first subset of candidate directions. The directions of regularity for pixels of this region of the second synthesized image are detected from the second subset of candidate directions. The recursive determination of the subsets of candidate directions provides a sparse geometry for efficiently analyzing the video sequence. | 01-23-2014 |
20130249967 | BACKLIGHT COMPENSATION PATTERN - For estimating an illumination pattern generated by the plurality of light sources, a combination of contributions of the light sources is computed. The contribution of a light source comprises a combination of at least a first component, comprising a part of a reference profile aligned on a position of said light source, said part of the aligned reference profile extending within the illumination area, and a second component depending on a distance between the position of said light source and an edge of the illumination area. | 09-26-2013 |
