Abstract: A system and method are provided for compressing a graphical representation that describes the appearance of an object from a plurality of viewing directions. Compressing includes accessing the graphical representation, removing redundant descriptive information from the graphical representation using sign consistent matrix factorization and approximation techniques, and representing the remaining information for efficient rendering, such as rendering with hardware-assisted computation.

Abstract: A system and method for recognizing gestures. The method comprises obtaining image data and determining a hand pose estimation. A frontal view of a hand is then produced. The hand is then isolated the background. The resulting image is then classified as a type of gesture. In one embodiment, determining a hand pose estimation comprises performing background subtraction and computing a hand pose estimation based on an arm orientation determination. In another embodiment, a frontal view of a hand is then produced by performing perspective unwarping and scaling. The system that implements the method may be a personal computer with a stereo camera coupled thereto.
