基于C++AMP的计算机图像视频处理
Computer Image and Video Processing Based on C++AMP
摘要
Abstract
With the rapid development of parallel computing technology,the amount of data to be processed is also increasing,so the in-crease of parallel computing becomes an urgent problem to be solved.In the processing of computer image,each link may need a lot of computing,and the C++AMP parallel computing can greatly improve the processing efficiency.For example in the surveillance video content processing,in order to get more clear image information,the image will be magnified.However,it will get a edge information af-ter image magnification,not clear and abnormal blur.Therefore,acquiring a clear image edge is much important for information acquisi-tion.For the monitoring image is difficult to identify,we put forward an image edge information processing method of improved Canny operator based on C++AMP.First we introduce the concept of C++AMP and the current processing method of Canny operator.The cur-rent Canny operator is optimized,and the Canny operator improved by C++AMP parallelization is studied.Then the improved gradient amplitude method is used to optimize the Canny operator.Form the comparison between the serial processing and the parallelization of Canny operator,we can see the advantage of the latter.The advantages are more obvious when the images are bigger.The edge will be wi-der and more obvious and the operation will get faster when the images are clearer.关键词
