Abstract: Methods and systems are presented for converting a mosaiced image in which, for each pixel, a single color intensity value is defined for only one corresponding color, into a full color image in which, for each pixel, color intensity values are defined for each of three colors. For each color, the intensity values of the mosaiced image are interpolated, and regression filtering is performed using the intensity values of one or both of the other colors. Residual values are found as the difference between the result of the regression filtering and the mosaiced image, and these are interpolated, and added to the output of the regression, to form a full color image. The process may be iterated. In each iteration, the regression is performed using the refined channel images generated in the previous iteration.

Abstract: Given a digital video clip, this invention describes how to efficiently compute the motion vectors and motion trajectory of each identified video object for facilitating various commonly encountered visual applications, such as video compression for transmission and archiving, security and surveillance monitoring, and search-by-query required in the Internet search engine or digital library.
