摘要： A method and apparatus transcode an image. An encoded input bitstream of the image is analyzed to obtain a structure of the encoded input bitstream, in which the image includes a region-of-interest and a background region, and in which the encoded input bitstream is a stream of packets. A first quality value for the region-of-interest and a second quality value for the background region are determined. An encoded output bitstream is composed from a subset of the packets selected from the encoded input bitstream according to the structure, in which the subset of packets includes a first set of packets corresponding to the region-of-interest having the first quality value, a second set of packets corresponding to the background region and having second quality value, and empty packets.

摘要： First biometric parameters are acquired from a user. Input data are encrypted according to the biometric parameters to produce ciphertext. The biometric parameters are encoded using a syndrome encoder to produce a syndrome code. The ciphertext and the syndrome code are associated with each other and stored in a computer readable media so that only the same user can subsequently decrypt the cipher text.

摘要： A method acquires compressed videos. Intra-, or inter-frames of each compressed video are acquired at a fixed sampling rate. Joint analysis is applied concurrently and in parallel to the compressed videos to determine a variable and non-uniform temporal sampling rate for each compressed video so that a combined distortion is minimized and a combined frame rate constraint is satisfied. Each compressed video is then sampled at the associated variable and non-uniform temporal sampling rate to produce output compressed videos having variable temporal resolutions.

摘要： A method performs inverse tone mapping of an image in a decoder. For each block of each color channel of the image a scaling factor is determined by adding a predicted scaling factor for the current block to a difference between the predicted scaling factor and the scaling factor of an adjacent block. An offset value for the current block is determined by adding a predicted offset for the current block to a difference between the predicted offset value and the offset value of the adjacent block. The scaling factor and the offset value are applied to pixel intensity values of the current block to produce a mapped block. The inverse tone mapping can also be applied to blocks of different sizes.

摘要： A adaptive complexity control algorithm is proposed to reduce the complexity of H.264 motion estimation. The main idea is to limit the complexity of motion estimation based on the expected RD coding gain loss. In order to efficiently reduce the complexity to desired level, ACC is designed to provide complexity scalability in motion estimation so as to provide flexible tradeoff between video quality and computational complexity. With the proposed algorithm, we demonstrate that complexity of motion estimation can be reduced by ¾ without significant RD performance degradation.

摘要： A method randomly accesses multiview videos. Multiview videos are acquired of a scene with corresponding cameras arranged at poses, such that there is view overlap between any pair of cameras. V-frames are generated from the multiview videos. The V-frames are encoded using only spatial prediction. Then, the V-frames are inserted periodically in an encoded bit stream to provide random temporal access to the multiview videos. Additional view dependency information enables the decoding of a reduced number of frames prior to accessing randomly a target frame for a specified view and time, and decoding the target frame.
