A method and apparatus that determines the topology of a sequence of images and then globally aligns the images with respect to each image's neighboring images. The apparatus includes a topology determination module, a local coarse registration module, a local fine registration module, a global consistency module, and a color matching/blending module. To accurately render a mosaic image from a sequence of images the topology determination and global alignment processes are iterated to progressively produce accurately aligned images. The apparatus efficiently and accurately combines a plurality of source images into a seamless panoramic mosaic representation of a scene, of arbitrarily wide spatial and angular extent, regardless of the order of image acquisition.

Method and apparatus for performing local to global multiframe alignment

A method and apparatus for storing a sequence of compressed frames of digital motion video information in a circular buffer is disclosed. In a preferred embodiment, compressed digital motion video information is written from a storage device to the circular buffer. A host pointer is set equal to the location corresponding to the end of the last frame of motion video information written to the circular buffer, and the positions of a microcode pointer and the host pointer are compared. Based on these positions, determinations are made regarding (i) whether a compressed frame of digital motion video information is present in the circular buffer and ready for decompression and (ii) whether a portion of the circular buffer can be re-written with compressed digital motion video data based on the positions of the microcode and host pointers.
