摘要： In a system and method for generating a synopsis video from a source video, at least three different source objects are selected according to one or more defined constraints, each source object being a connected subset of image points from at least three different frames of the source video. One or more synopsis objects are sampled from each selected source object by temporal sampling using image points derived from specified time periods. For each synopsis object a respective time for starting its display in the synopsis video is determined, and for each synopsis object and each frame a respective color transformation for displaying the synopsis object may be determined. The synopsis video is displayed by displaying selected synopsis objects at their respective time and color transformation, such that in the synopsis video at least three points that each derive from different respective times in the source video are displayed simultaneously.

摘要： A computer-implemented method and system determines camera movement of a new frame relative to a sequence of frames of images containing at least one dynamic object and for which relative camera movement is assumed. From changes in color values of sets of pixels in different frames of the sequence for which respective locations of all pixels in each set are adjusted so as to neutralize the effect of camera movement between the respective frames in the sequence containing the pixels, corresponding color values of the pixels in the new frame are predicted and used to determine camera movement as a relative movement of the new frame and the predicted frame. An embodiment of the invention maintains an aligned space-time volume of frames for which camera movement is neutralized and adds each new frame to the aligned space-time volume after neutralizing camera movement in the new frame.

摘要： Natural looking output images are computed from input images based on given user constraints. Pixels in the output images are assigned a shift such that the respective output pixel value is derived from the value of the input pixel whose location is related to that of the output pixel by the shift, at least one shift being non-zero. The shift is determined by an optimization process adapted to minimize a cost function that includes a data term on the shifts of single pixels and a smoothness term on the shifts of pixel pairs. The output image is computed by applying the optimized shift-map between the input and output pixels. The data term can include shift constraints that limit the location in the output images of selected input pixels, and saliency constraints, indicating a preference that selected pixels in the input images will or will not appear in the output image.

The panoramic image generator is configured to mosaic together respective left and right image strips from respective ones of a plurality of images to form the respective left and right panoramic images. The panoramic image generator is configured to use strip separation values for the respective images to determine the separation of the respective left and right image strips in generating the respective left and right panoramic images. The strip separation value generation module is configured to generate, for respective ones of said images, the strip separation values so as to provide at least one selected disparity for objects in the panoramic scene.
