Abstract

The invention discloses a morphological image edge detecting method based on the quantum theory. The method comprises the following steps that S1, morphological edge detection is carried out based on the quantum theory; S2, edge thinning is carried out on an image in the mode of combining an NMS thinning algorithm and morphological thinning; S3, edge connection is carried out on the image through a quantum probabilistic method. When a quantum morphological edge detecting algorithm provided in the scheme is used for carrying out edge detection on a noise image, even though the strength of noise is large, the edge can be effectively extracted. Edge continuity can be effectively improved through an edge connecting algorithm based on quantum probability in the scheme.

Description

technical field [0001] The invention relates to the technical field of graphic edge processing, in particular to a quantum theory-based morphological image edge detection method. Background technique [0002] Edge detection is a basic image processing method, which has been widely used in image segmentation, image recognition and image analysis and other fields. Generally, in the process of image acquisition, transmission and processing, there will always be various noises inevitably, and the noise is mixed with the frequency bands at the edge of the image, which makes image edge detection difficult. Therefore, how to effectively obtain the image edge from the image disturbed by noise is an important research topic in image processing. [0003] Traditional edge detection methods based on Sobel, Roberts, Prewitt and other gradient operators and Laplacian operators are very sensitive to noise, and it is difficult to effectively detect the edge of noisy images. The Canny oper...
