CUDA facilitates the development of General Purpose computing on Graphics Processing Units (GPGPU), however, its complex memory system, thread-level structure, and data transmission control between memories have brought great challenges for programming on GPU. In order to facilitate the development of parallel programs on GPU and reuse existing sequential codes, in this paper we propose a novel directive...
The interval and the density valve are need to input in traditional clustering methods that based on grid and density method, result in unsmoothed cluster, wrong judgment of clustering boundary. A clustering approach was proposed, which can confirm the interval and the number of clustering, reasonable cluster the object and create the Hilbert R-tree using the result of clustering. Experiment result...
A fast algorithm is proposed to restore the color images, degraded in a deterministic way by motion- blurred,by multichannel combination processing. Based on the color space conversion model, the point spread functions of the image motion on each plane of YUV422 image can be achieved.The U, V plane of YUV422 images are combined to form a newel plane which has the same size as Y plane. Then, the Y,...
