CUDA架构下的快速图像去噪

Fast image denoising with CUDA

图像处理通常需要较大的计算量,其中图像去噪是经常使用的一种预处理算法,研究其快速算法具有重要意义。图形处理器具有强大的并行计算能力,但大部分时间处于闲置状态。统一计算设备架构提供了一种简单易用的开发环境,可利用图形处理器进行通用计算。提出了基于统一计算设备架构的快速图像去噪算法,可以利用GPU的计算能力,加快去噪过程,显著地减少计算时间。

The huge computation load is necessary, commonly for the image processing,the research on the fast algorithm of image denoising is very important for it is often used in the field.GPU（Graphic Processing Unit） is powerful for Data-Parallel Processing but it is idle for the most of time.CUDA（Compute Unified Device Architecture） is a simple and easy to use for the general purpose eomputation.A fast algorithm of image denoising is proposed based on the CUDA,it uses the power of GPU to accelerate the process of image denoising and reduce the time significantly.
