摘要： Color trim data is used in an approximation function to approximate one or more non-linear transformations of image data in an image processing pipeline. The color trim data is derived in one embodiment through a back projection on a colorist system, and the color trim data is used at the time of rendering an image on a display management system.

摘要： Methods and systems for enhancing motion estimation are disclosed for stereoscopic video sequences. The motion vector parameters and disparity values for consecutive frames may be calculated to estimate motion in a coherent manner between two channels, such as a left channel and a right channel in stereoscopic images. Occlusion handling is also applied to improve the estimation.
