Abstract: An apparatus and method for deriving a motion vector predictor or a motion vector predictor candidate or a motion vector or a motion vector candidate for a current block are disclosed. In video coding systems, the spatial and temporal redundancy is exploited using spatial and temporal prediction to reduce the information to be transmitted or stored. Motion Vector Prediction (MVP) has been used to further conserve the bitrate associated with motion vector coding. The MVP technique being developed for the current HEVC only considers the motion vector having the same reference list and the same reference picture index as the current block to be an available spatial motion vector predictor candidate. It is desirable to develop a MVP scheme that can improve the availability of the motion vector predictor candidate based on motion vectors from the spatially neighboring block.

Abstract: The present disclosure relates to methods for fabricating LEDs by patterning and etching an n-doped epitaxial layer to form regions of roughened surface of the n-doped layer and mesa structures adjacent to the roughened surface regions before depositing an active layer and the rest of the epitaxial layers on the mesa structures. The method includes growing epitaxial layers of an LED including an un-doped layer and an n-doped layer on a wafer of growth substrate. The method also includes patterning the n-doped layer to form a first region of the n-doped layer and a mesa region of the n-doped layer adjacent to the first region. The method further includes etching the first region of the n-doped layer to create a roughened surface. The method further includes growing additional epitaxial layers of the LED including an active layer and a p-doped layer on the mesa region of the n-doped layer.

Abstract: An apparatus and method for video coding and decoding with constrained PU partition are disclosed. In the High Efficient Video Coding (HEVC) system, rate-distortion function or other performance criterion usually is evaluated for various CU partition and PU partition during the encoding process in order to select a configuration with best possible performance. The PU design in the current HEVC development results in some redundancy that causes rate-distortion function or other performance criterion repeatedly evaluated for same PU configuration. Accordingly, constrained PU partition is developed to eliminate or reduce the redundancy in processing. Furthermore, necessary syntax to convey the information related to constrained PU partition between an encoder and a decoder is developed.

Abstract: The invention provides an image processing apparatus for processing an interlaced video which includes a judging module, a determining module and a processing module. The judging module is used for judging if a pixel in the kth frame among P frames of the interlaced video relates to a moving object. If the result judged by the determining module is YES, the determining module determines one between two pixels adjacent to the judged pixel in the frame as an edge pixel relative to an edge of the moving object. The first processing module is used for calculating a gray scale of the edge pixel determined by the determining module in an average way.

A method for fabricating a vertical light emitting diode (VLED) die includes the steps of: providing a carrier substrate; forming an n-type confinement structure on the carrier substrate having at least one etch stop layer; forming an active layer on the n-type confinement structure; forming a p-type confinement layer on the active layer; and removing the carrier substrate.

Abstract: In the current high efficiency video coding development, each LCU has its own quantization parameter (QP) and the difference between a current QP and a reference QP is transmitted instead of the QP value itself. Since the LCU is much larger than the macroblock of AVC/H.264, using one delta QP per LCU may cause rate control unable to adapt to the bitrate quickly enough. Consequently there is a need to adopt delta QP in units smaller than LCU to provide more granular rate control. Furthermore, it is desirable to develop a system that is capable of facilitating more flexible delta QP. Accordingly, adaptive quantization parameter processing is disclosed where a QP minimum CU size for incorporating or deriving a delta QP is indicated selectively in the slice level or in the sequence/picture level. In one variation, the delta QP is incorporated or derived only if nonzero quantized transform coefficients exist in a leaf CU that is larger than the QP minimum CU size.

Abstract: In the H.264/AVC standard, one of the new characteristics is the possibility of dividing an image in regions called slice groups. The use of slice groups provides various possible advantages such as prioritized transmission, error resilient transmission, and etc. The slice groups can be formed by flexible macroblock ordering (FMO), where each picture can be divided into slice groups in different scan patterns of the macroblocks. In the high efficiency video coding (HEVC) under development, a more flexible block structure, called coding unit (CU), is used as the unit to process video data. The picture is first divided into largest CUs (LCUs) and each LCU is adaptively split into smaller CUs using a quadtree until leaf CUs are reached. In the current HEVC development, there is neither slice nor slice group structure being considered. The LCU size used for HEVC is 16 times as large as the macroblock size used in the H.264/AVC standard.

The group III-V semiconductor structure includes a thick gallium nitride layer of at least 100 microns or a light-emitting structure.

Abstract: An apparatus and method for video coding based on flexible slice structure are disclosed. In the recent high efficiency video coding (HEVC) development, the slice may contain multiple LCUs instead of macroblocks. The LCU size being considered is 64×64 pixels which is much larger than the macroblock size of 16×16 pixels. Compared with the macroblock aligned slice for H.264, the LCU-aligned slice for HEVC does not provide enough granularities for dividing video frames. Consequently, a flexible slice structure is developed where slice partition is based on smaller coding units. In the flexible slice structure, the first LCU and the last LCU of the slice are allowed to be a fractional LCU, which is derived from a whole LCU using quadtree partition. Syntax elements are also developed to enable conveyance of flexible slice structure between an encoder and a decoder efficiently.

Abstract: An apparatus and method for video coding having intra-slice deblocking, intra-slice adaptive loop filter, and intra-slice adaptive offset are disclosed. In a video coding system, a picture is often divided into slices and each slice is independently processed so that errors or missing data from one slice cannot propagate to any other slice within the picture. In the recent high efficiency video coding (HEVC) development, deblock filtering (DF), adaptive loop filter (ALF) and adaptive offset (AO) may be applied to reconstructed slices. When the processing is applied across slice boundaries, it may rely on pixels outside the current slice and cause dependency of the current slice on other slice(s). Consequently, the DF/ALF/AO processing on a reconstructed slice may have to wait until the reconstructed slices that it is dependent from complete the DF/ALF/AO processing. To overcome the slice boundary issue, intra-slice DF/ALF/AO is developed that does not rely on any pixel outside the currently slice.

Abstract: In a block-based motion compensated system, coding noises may arise due to lossy operations. Adaptive loop filter (ALF) is a technique used to improve the quality. A pixel adaptive (PA) ALF method was developed that uses the Sum-modified Laplacian Measure (SLM) to classify pixels and applies a respective ALF filter to each pixel according to the SLM. While the PA ALF achieves better performance over a conventional single filter (SF) based ALF, the PA ALF causes higher complexity and consumes more power due to the high complexity and per-pixel filter switching. Accordingly region based ALF scheme is disclosed which allows adaptive filter selection on a region by region basis and does not require per-pixel filter switching. In one embodiment according to the present invention, a picture is divided into M×N regions. The region based ALF also allows region merging for the M×N regions to improve performance.

Abstract: A method and apparatus for processing in-loop reconstructed video using an in-loop filter is disclosed. In the recent HEVC development, adaptive loop filtering (ALF) is being adopted to process in-loop reconstruction video data, where ALF can be selectively turned ON or OFF for each block in a frame or a slice. An advanced ALF is disclosed later that allows a choice of multiple filter sets that can be applied to the reconstructed video data adaptively. In the present disclosure, pixels of the in-loop reconstructed video data are divided into a plurality of to-be-filtered regions, and an in-loop filter from a filter set is determined for each to-be-filtered region based on a rate-distortion optimization procedure. According to one embodiment of the present invention, computation of cost function associated with the rate-distortion optimization procedure is related to correlation values associated with original video data and the in-loop reconstructed video data.
