In publishing and printing of network version field, there are enormous number of TIFF format (CMYK) images which requires too huge space for storing and enough bandwidth for transmitting. Therefore, common need to manipulate huge amount of data brought about the issue of fast lossless compression. 2D integer wavelet transform can be used for lossless compression of static image, such as, 5/3 lifting...
While the computational power of Field Programmable Gate Arrays (FPGA) makes them attractive as code accelerators, the lack of high-level language programming tools is a major obstacle to their wider use. Graphics Processing Units (GPUs), on the other hand, have benefitted from advanced and widely used high-level programming tools. This paper evaluates the performance, throughput and energy of both...
Detailed research is conducted on video texture for 3D movie play application and current research situation, problem and challenge in the world are analyzed in this paper. Then an effective solution is presented. Direct Show is used to manage the video data while Direct 3D serves as graphic rendering API. This paper extracts the parallel computing module from the fixed rendering pipeline and takes...
We propose a novel hardware design for decoding compressed floating-point textures in a graphics processing unit (GPU). Our decoder is based on the NXR texture format, which provides lossy, fixed-rate 6:1 compression for floating-point textures. Our design exploits the constraints of the compressed pixel blocks to produce the correct output using only fixed-point arithmetic. This results in significantly...
Error concealment restores the visual integrity of image content that has been damaged due to a bad network transmission. Best neighborhood matching (BNM) is an effective image recovery method that exploits the information redundancy in a block-coded broken image to find similar content which it then uses to repair or conceal errors. On a high definition image BNM is traditionally implemented sequentially,...
