    摘要： Methods for correcting an image acquired through an Ultra Wide-Angle (UWA) lens is disclosed, where the entire image is mapped via a transformation that substantially improves the perspective, yet maintains all image information. Additional locally adaptive transformations can be applied to regions of interest in the image to fully restore the perspective. This de-warping scheme allows for flexible manipulation of the image while no content would be lost.

    摘要： In some embodiments, a video decoder is capable of recovering skipped video data (e.g. motion vectors, prediction modes, quantization parameters, selected frequency-domain coefficients such as DC and 5-lowest-frequency AC coefficients, and/or entire video data blocks) using multiple alternative recovery modes such as spatial interpolation, temporal interpolation, and motion search. To decide whether to skip a particular data type for a block, the encoder evaluates the effect of skipping the data on rate and distortion by simulating the decoder data recovery using the multiple recovery modes. The encoder transmits indicators of skipped data types and associated recovery modes, if different from decoder baselines. The skipped data and recovery mode indicators may be included in macroblock and/or slice headers, and/or as part of sequence, group-of-picture (GOP), or picture coding parameter data. Skipped data recovery decoder resources (e.g. motion search logic) may be used for recovering data lost due to transmission errors.

    摘要： Described systems and methods allow a reduction in the memory bandwidth required in video coding (decoding/encoding) applications. According to a first aspect, the data assigned to each memory word is chosen to correspond to a 2D subarray of a larger array such as a macroblock. An array memory word organization allows reducing both the average and worst-case bandwidth required to retrieve predictions from memory in video coding applications, particularly for memory word sizes (memory bus widths) larger than the size of typical predictions. According to a second aspect, two or more 2D subarrays such as video predictions are retrieved from memory simultaneously as part of a larger 2D array, if retrieving the larger array requires fewer clock cycles than retrieving the subarrays individually. Allowing the combination of multiple predictions in one memory access operation can lead to a reduction in the average bandwidth required to retrieve predictions from memory.

    摘要： Systems and methods for folding a single instruction multiple data (SIMD) array include a newly defined processing element group (PEG) that allows interconnection of PEGs by abutment without requiring a row or column weave pattern. The interconnected PEGs form a SIMD array that is effectively folded at its center along the North-South axis, and may also be folded along the East-West axis. The folding of the array provides for north and south boundaries to be co-located and for east and west boundaries to be co-located. The co-location allows wrap-around connections to be done with a propagation distance reduced effectively to zero.
