一种基于 GPU 的二维离散多分辨率小波变换加速方法
A Method of GPU-Based Accelerating 2D Multi-resolutions Discrete Wavelet Transform
摘要
Abstract
Since the classical wavelet transform algorithm on CPU hardly meets the real-time performance requirements,especially dealing with large scale data in high resolution,we presented a GPU-based parallel wavelet transform algorithm,which improves the locality of local memory access and increases the bandwidth of global memory access.It uses multi-kernel to improve the performance in the case of multi-resolutions.The experiment results show that compared to the performance of a classical algorithm on CPU,GPU gains the speedup of 30—60,accordingly,it can satisfy the real-time requirements for transformation.关键词
