Canny Edge Detection on NVIDIA CUDA
The Canny edge detector is a very popular and effectiveedge feature detector that is used as a pre-processing stepin many computer vision algorithms. It is a multi-step detectorwhich performs smoothing and filtering, non-maximasuppression, followed by a connected-component analysisstage to detect edges, while suppressing nonedge filter responses. While there have been previous (partial)implementations of the Canny and other edge detectorson GPUs, they have been focussed on the old style GPGPUcomputing with programming using graphical applicationlayers. Using the more programmer friendly CUDA framework,we are able to implement the entire Canny algorithm.Details are presented along with a comparison with CPUimplementations. We also integrate our detector in to MATLAB,a popular interactive simulation package often usedby researchers. The source code will be made available asopen source.Paper
