    摘要: Disclosed is an apparatus and method for generating a real-time stereoscopic image from depth map. According to the depth information of the image, a depth-image-based rendering (DIBR) algorithm is used to shift (or move) the position of the object in the image to generate the stereoscopic image with parallax. When the object is shifted (or moved) away from its original position, a hole will occur in the original position. Therefore an image inpainting algorithm is developed to fill the hole. In order to achieve the real-time application, a hardware architecture and method have been developed to accomplish the DIBR and image inpainting algorithm.

    摘要: The present invention provides a high-speed, memory efficient parallel coding technique for embedded block coding with optimized truncation (EBCOT) used in still image compression. Attributing to parallel processing method and structure, it processes a discrete wavelet transform (DWT) coefficient at a clock cycle without any state variable stored. Therefore, the need of state variable memory can be avoid and the external memory bandwidth can be reduced. With the same cost of chip-area and lower power consumption, the processing rate of this invention is several times higher than conventional schemes. Furthermore, the present invention processes 50 M coefficients per second at 100 MHz and can encode lossless HDTV 720p resolution pictures at 30 fps in real time.
