Abstract: Provided is a method that generates a prediction block of a current prediction unit, and generates a residual block of the current prediction unit. To generate the prediction block, a reference picture index and motion vector difference of the current prediction unit are obtained from a received bit stream, spatial and temporal motion vector candidates are derived to construct a motion vector candidate list. A motion vector predictor is selected and a motion vector of the current prediction unit is restored to generate the prediction block. Therefore, the motion vector encoded effectively using spatial and temporal candidates is correctly recovered and the complexity of a decoder is reduced.

Abstract: A video decoder receives data representing an encoded image frame partitioned into one or more partitions. The video decoder stores the motion vector associated with each partition. For partitions of size (k*S), k being an integer, and S being the smallest allowed size for a partition, the video decoder stores (k) separate entries of a same value as the value of the motion vector of the corresponding partition. When performing motion compensation to reconstruct the encoded macro-block, such a manner of storing enables the video decoder to retrieve pixel values of best-match partitions associated with each of the corresponding ones of the one or more partitions without having to process partition information specifying the type of the partitions.

Abstract: Provided are a method and apparatus for entropy-encoding/entropy-decoding video data. The method of entropy-encoding video data includes binarizing coefficients of the frequency domain, which are generated by transforming a residual block of a current block into the frequency domain, using different binarization methods and performing binary arithmetic coding on the binarized coefficients. In this way, the coefficients are binarized adaptively according to whether the frequencies of the coefficients are high or low, thereby improving the compression efficiency of the video data.

Abstract: A method for decoding an image according to the present invention comprises the steps of: restoring a residual block by performing inverse quantization and inverse transformation for the entropy-decoded residual block; generating a prediction block by performing intra prediction for a current block; and restoring an image by adding the restored residual block to the prediction block, wherein the step of generating the prediction block further comprises a step for generating a final prediction value of a pixel to be predicted, on the basis of a first prediction value of the pixel to be predicted, which is included in the current block, and of a final correction value that is calculated by performing an arithmetic right shift by a binary digit 1 for a two's complement integer representation with respect to an initial correction value of the pixel to be predicted. Thus, the operational complexity during image encoding/decoding can be reduced.

Abstract: Dynamic projection of at least first and second patterns contributes detectable disparity onto a scene that includes a target object. The scene is imaged with two-dimensional cameras whose acquired imagery includes disparity contributions whose presence enable a three-dimensional reconstruction depth map to be rapidly and accurately generated. In one embodiment coherent light is input to a first DOE within whose near range output is disposed a second DOE, whose far range output projects an image. Electronically varying effective optical distance between the two DOEs varies the pattern projected from the second DOE. A processor system and algorithms enable dynamic intelligent selection of projected patterns to more readily discern target object characteristics: shape, size, velocity. Patterns can implement spatio-temporal depth reconstruction, spatio-temporal depth reconstruction, and even single-camera spatio-temporal light coding reconstruction.
