Abstract: A number of input images of a scene is taken from different viewpoints. A respective model of the scene is made for each input image. The model contains descriptions of the location of surface patches in the space of the scene, substantially each surface patch corresponding to a set of pixels in the input image. A viewpoint is selected and views are taken from the viewpoint, each of a respective input images according to the corresponding model. For each pixel in an output image one of the views is selected and a pixel from the selected view is displayed at the pixel in the output image.

Abstract: Each pixel in an image has its own color value that is defined in a color look-up table. Regions of the image are separated into groups with similar color values. For each group, the color of one of the pixels is selected. The image is compressed by retaining only references to the color look-up table that define the color values of the pixels selected for the groups and a pixel map which indicates for each pixel, the group to which the pixel belongs among the groups which constitute the region. Upon decompression, each pixel is shown with the color of the pixel that was selected for the group to which the pixel belongs.
