CUDA加速工业DR图像分割
Speedup segmentation of industrial DR image by CUDA
摘要
Abstract
The segmentation of industrial DR image is very important to industrial image processing. C-V method has some advanage to industrial DR image segmentation. Due to higher complexity, C-V method is rarely applied in a timecritical industrial environment. This paper presented an efficient parallel implementation of DR image segmentation by C-V method with CUDA, and used a method that separated data computing merged in corresponding thread by shared memory. Finolly, compared the results to the, current applications on image processing workstation, the implementation exhibited a speedup of 32 to 44 times compared to a state-of-the-art CPU.关键词
