摘要： An apparatus to remove an input offset voltage of a comparator circuit includes an input voltage offset capacitor, control logic to charge and discharge the capacitor to provide an offset cancelation voltage. The offset cancellation voltage removes the input offset voltage of the comparator dependent upon an output of the comparator circuit. A switching arrangement controlled by the control logic switches signals between the capacitor and the control logic.

摘要： An image converter compiles three-dimensional content into a data store, identifies a number of stereo image pairs from the three-dimensional content, computes a depth map for each of the stereo image pairs from the three-dimensional content, and partitions the stereo image pairs in the data store into multiple categories. The image converter determines a depth cue for each of the categories based on the depth map for each of the stereo image pairs in each category. The image converter computes a depth map for a category associated with a two-dimensional input image based on the determined depth cue and renders a three-dimensional output image from the two-dimensional input image using the depth map for the category.

摘要： A level shifter includes a latch supplied at a first voltage, and first and second series connections of first and second switch elements and first and second biased elements in series with first and second branches of the latch respectively. Third and fourth switch elements are connected in parallel with the first and second series connections respectively. The input signal, at a voltage different from the first voltage, activates the third or fourth switch element during a transition period after a change of state of the input signal one way or the other to change the state of the latch, and deactivates the third or fourth switch element and activates the first or second switch element to maintain the state of the latch during a stabilization period following the transition period. The transition periods are shortened, reducing current consumption and transfer delay times.

摘要： The present invention provides a method to compress digital moving pictures or video signals based on an overcomplete basis transform using a modified Matching Pursuit algorithm. More particularly, this invention focuses on the efficient coding of the motion residual image, which is generated by the process of motion estimation and compensation. A residual energy segmentation algorithm (RESA) can be used to obtain an initial estimate of the shape and position of high-energy regions in the residual image. A progressive elimination algorithm (PEA) can be used to reduce the number of matching evaluations in the matching pursuits process. RESA and PEA can speed up the encoder by many times for finding the matched basis from the pre-specified overcomplete basis dictionary. Three parameters of the matched pattern form an atom, which defines the index into the dictionary and the position of the selected basis, as well as the inner product between the chosen basis pattern and the residual signal. The present invention provides a new atom position coding method using quad tree like techniques and a new atom modulus quantization scheme. A simple and efficient adaptive mechanism is provided for the quantization and position coding design to allow a system according to the present invention to operate properly in low, medium and high bit rate situations. These new algorithm components can result in a faster encoding process and improved compression performance over previous matching pursuit based video coders.

摘要： A new effective and fast method and apparatus for still image compression implements an embedded progressive sorting scheme in a quadtree-like structure. In contrast to zerotree-based methods for wavelet coding, the invented embedded quadtree wavelet (EQW) method exploits the inherent spatial self-similarity within individual layers of the multiresolution decomposition hierarchy. This self-similarity offers higher predictability of the data within the same resolution level, and therefore usually provides a higher performance in seeking a compact code. The computation involved in the EQW method is more efficient than in the zerotree wavelet coding, and the produced bitstream is more robust to channel noise. The present invention can effectively be used for object-oriented shape coding or region coding in image and video compression coding systems.

摘要： A system provides product annotation in a video to one or more users. The system receives a video from a user, where the video includes multiple video frames. The system extracts multiple key frames from the video and generates a visual representation of the key frame. The system compares the visual representation of the key frame with a plurality of product visual signatures, where each visual signature identifies a product. Based on the comparison of the visual representation of the key frame and a product visual signature, the system determines whether the key frame contains the product identified by the visual signature of the product. To generate the plurality of product visual signatures, the system collects multiple training images comprising multiple of expert product images obtained from an expert product repository, each of which is associated with multiple product images obtained from multiple web resources.
