摘要
NVIDIA公司提出的CUDA技术通过并发执行多个线程以实现大规模快速计算的能力。在研究CUDA技术在数字图像处理领域应用的基础上,提出了一种基于NVIDIA CUDA的方法实现图像边缘检测,把CUDA技术的快速计算的能力应用到数字图像处理领域。从CUDA技术的概况的介绍出发,对基于NVIDIA CUDA的图像边缘检测方法以及该方法的详细实现过程进行了形式化的描述,解决了基于CPU的传统图像边缘检测方法运行效率低的问题。实验结果证明CUDA在数字图像处理的实际应用中卓有成效。
Recently GPU has acquired programmability to perform general purpose fast computation by running ten thousands of threads concurrently. The CUDA technology which provided by NVIDIA Corporation is the new kind of technology in this field. For studying and developing the application of CUDA in digital image processing, this pa- per presents a method for image edge detection on NVIDIA CUDA architecture. First make a description＇ of CUDA, then explain explicitly the realizing of the new method, solve the problem of low efficiency of the image edge detection based on CPU. The experimental results show that the CUDA is practical for some applications of imagine processing.
