Embodiment

[0014] The image contour extraction method with high anti-interference ability of the present invention includes chain code tracking and storage contour information algorithm, and also includes the following steps:

[0015] S1, using grayscale transformation to change the color image into a grayscale image, and perform nonlinear transformation;

[0016] S2, perform morphological processing on the image, first expand and then corrode;

[0017] S3, smoothing the image;

[0018] S4, after binarizing the image, extract the image contour in combination with the chain code tracking and storing contour information algorithm. S1 is used to achieve dimensionality reduction. Usually, each pixel of a color image is represented by 3 values. Grayscale transformation is used to transform from 3×255 combinations to only 255 combinations. Non-linear transformation can better highlight or suppress the image. information; S2 performs morphological processing on the image to eliminate interfer...

Abstract

The invention discloses an image contour extraction method with high anti-interference capability, and relates to an image contour extraction method. The method comprises a chain code tracking storagecontour information algorithm, and further comprises the following steps: S1, converting a color image into a gray level image by utilizing gray level conversion, and performing nonlinear conversion;S2, performing morphological processing on the image, and performing expansion and corrosion in sequence; S3, performing smoothing processing on the image; and S4, binarizing the image, and extracting the image contour in combination with the chain code tracking storage contour information algorithm. Exponential transformation is adopted in the nonlinear transformation. The method can effectivelyimprove the contour detection precision.

Description

technical field [0001] The invention relates to an image contour extraction method, in particular to an image contour extraction method with high anti-interference ability. Background technique [0002] Contour extraction methods usually rely on high-order operators for analysis. Because the high-order operators are simulated and intuitive, it is difficult for the naked eye to judge whether the contour extraction is good or bad. In fact, there are many noise points, which have a great impact on the restoration operator. Contents of the invention [0003] The technical problem to be solved by the present invention is that the anti-interference ability of the existing image contour extraction method is insufficient, and the purpose is to provide an image contour extraction method with high anti-interference ability to solve the above-mentioned problems. [0004] The image contour extraction method with high anti-interference ability includes chain code tracking and storage c...
