Abstract

Aiming at the problem that the existing gradient operator is sensitive to noise in image edge detection, this paper proposed an improved Gaussian-Laplacian edge detection method. Edge detection in noisy images was a key task. However, several commonly used gradient operators, including the proposed Gaussian-Laplace operator, had failed to achieve the desired results. The proposed method improved the traditional Laplacian edge detection operator and combined it with a Gaussian filter. First, it used a Gaussian filter to smooth the image and suppress noise. Then it performed edge detection based on a Laplacian gradient edge detector. Finally, it selected 10 images in the imagenet data set. It compared the Gaussian gradient edge detector proposed with the traditional edge detector. The evaluation results show that the PSNR obtained by the proposed method is higher than that of the comparison algorithm, and the mean square error(MSE) is smaller. Experimental results show that the proposed method can effectively improve the quality of noise image edge detection in practical applications.
