In this paper a parallel hardware structure of ASIC for HEVC intra prediction encoding is proposed. This structure by analyzing software algorithm, according to the characteristics of the ASIC implementation of parallelization, designs the DC, a planar, horizontal and vertical Angle prediction hardware structure of the parallel processing, and finished the calculation of SATD. A parallel prediction...
Vector quantization (VQ) is widely used in the field of image coding because of its simple decoding algorithm and high compression rate. But owing to its high complexity of image codeword matching process, it is often limited out of some place requisite of real time. In order to accelerate this process, a novel direction classifying criterion is presented in this paper, it is based on the good image...
A kind of low complexity inter-frame coding algorithm based on vector quantization (VQ) is presented in this paper. There are three inter encode modes according to the motion type of the image block. Not-encode mode is adopted by static block, residual mean coding mode is adopted by the smooth motion block, VQ and mean encode mode are adopted by general motion block. The motion type of the image block...
Abstract-Traditional image compression methods handle vectored data to compress, but the process undermines the spacial intrinsic structures of high dimensional data. In order to overcome the shortcomings of traditional methods, we presented a novel method of color image compression. In this paper, the color images were encoded into 3rd-order tensors (AI1timesI2timesI3). We did the tucker decomposition...
