摘要： Enhanced directional prediction apparatus and methods are taught which are based on edge-based adaptive directional estimation, for providing an improved prediction direction for intra prediction within a coding device. Image gradient vectors are obtained for pixels in the neighborhood of the current block, and edge directions determined. Candidate edge directions are processed to derive a dominant edge direction in response to defining an objective function as a summation of projections to a candidate direction and computing suggested direction of each neighboring pixel. The dominant edge direction may be utilized for the prediction direction, such as in response to a detection mode flag signaled to the decoder, or modified by an angular adjustment, which can be communicated to a decoder.

摘要： Reordering of a bitstream is able to be used to speed up the decoding in embedded graphics coding. In the reordering, the signaling bits of all of the groups are sent and then the refinement bits of each group follow. With this reordering, the decoder can decode the header, identify the number of refinement bits for each group and locate the starting point of each group within the bitstream, therefore parallel processing of each group is able to be implemented at the decoder side.

摘要： Adaptive entropy encoding and decoding utilizing set partitioning within generalized hierarchical trees which is applicable to both embedded and non- embedded encoding. After decorrelation and quantization during encoding, a tree structure is selected from multiple candidates, based on geometric relationships within the image block, for coding the coefficients toward improving coefficient zero clustering. The tree structure has leaf and non-leaf nodes in a specified arrangement, with leaf nodes containing coefficients associated with each non-leaf node. By proper tree selection, the number of zero clustered coefficients which may be eliminated from the encoded output stream is increased. During decoding, a tree structure compatible with the encoding for the current block is used for decoding the existing coefficients from the symbol stream and restoring missing zero coefficients.

摘要： Processes for compressing images with sparse histograms are disclosed. The image is divided into blocks, and a bit budget is assigned for each block. The pixels of a block are converted and coded bit-plane by bit-plane, starting from the Most Significant Bit (MSB) and going towards the Least Significant Bit (LSB). The pixels of the block are partitioned into groups. Each group contains pixels that have same value. Moving from the MSB to the LSB, the groups in each bit-plane are processed. When processing a group, the encoder sends a "0" if all group members have same bit value at the current bit-plane being processed, followed by the bit value; otherwise, the encoder sends a "1", followed by refinement bits for each pixel of the group, and the encoder splits the group.

摘要： Semi-automatic (instant) color image segmentation is performed on an input image for an object located near the point given by the user (e.g., touch screen contact). The size, shape, and the number of colors of the target object which is about (lying around or surrounding) the user-selected point is determined, and determinations made for which region the pixels belong to, either foreground or background. A binary object mask is generated which can be utilized for removing the material surrounding that object, or inverting the mask to remove the material of the object.

摘要： A method of and system for encoding high definition video content using embedded graphics coding is described. The method determines if the video content includes an RGB or YUV444 color format or a YUV422 color format. If the color scheme includes RGB or YCbCr444 data and separate encoding is used, then all three color components are encoded separately using scalar EGC. If the color scheme includes RGB or YCbCr444 data and joint encoding is used, then all three color components are jointly encoded using joint scalar EGC. If the color scheme includes YCbCr422 data and separate encoding is used, then Y, U and V are encoded separately using scalar EGC. If the color scheme includes YCbCr422 data and joint encoding is used, then Y is encoded by itself using scalar EGC and U and V are jointly encoded using joint scalar EGC.

摘要： Dual-mode compression of images/videos for reliable real-time transmission includes a scalable block-based video compression. The method provides graceful quality degradations in case of channel bandwidth changes. Prediction for encoding is avoided, and the process is less complex with less memory requirements. The method involves processing each block independently with the advantage that errors are not able to propagate beyond current block boundaries. Two different encoding modes are used, natural image coding for acquired images and graphics coding for computer generated images. The proper encoding mode is chosen by comparing performance of the two modes for a particular block to be encoded. An embedded bitstream is generated by the encoder in accordance to the available channel bandwidth.

摘要： An object segmentation system that includes a first type of sensor, a second type of sensor and a control circuitry. The first-type of sensor captures a sequence of color image frames of a scene. The second-type of sensor captures a depth image for each corresponding color image frame of the sequence of color image frames. The control circuitry generates a point cloud for an input color image frame. The control circuitry segments a foreground human object from a background of the input color image frame. The control circuitry detects a ground plane for the scene captured in the input color image frame. The control circuitry recovers a feet region in a defined region from a level of the detected ground plane. The control circuitry extracts the foreground human object with the recovered feet region from the background of the input color image frame, based on the detection of ground plane.
