An Improved NMS-Based Adaptive Edge Detection Method and Its FPGA Implementation
For improving the processing speed and accuracy of edge detection, an adaptive edge detection method based on improved NMS (nonmaximum suppression) was proposed in this paper. In the method, the gradient image was computed by four directional Sobel operators. Then, the gradient image was processed b...
