  • Abstract
    Recently there has been a great deal of interest in morphing techniques to produce intermediary images between two images. These techniques combine 2D interpolations of shape and color to make realistic special effects. The authors simulate view morphing, using sprites with depth about a pair of partially occluded images based on the epipolar geometry. The epipolar constraints improve the accuracy of the estimated disparity maps. To compute a depth map between two images, we use use a simple stereo system. Depth can be estimated from the disparity of corresponding points and is inversely proportional to disparity, used when sprites are composed. A sprite is an image with the standard three-color components (red, green, blue) and an additional channel that encodes the image´s shape. In the case of a pair of partially occluded images, whether there should be decomposed sprites to an image is the reason for attributing to reduce two problems (folds and holes), in the view morphing procedures
