Image contour extraction is the most important part of machine vision.Aimed at the problem of point-break of traditional method of contour extraction

Radon transform is given to reconstruct the outline of the breakpoint.And obtain continuous image contour.The principle and realization method of key technology are given.Matlab simulation experiment results show that the reconstructed image by Radon transform has the characteristics of wide single-pixel outline

a row

and continuous.It has certain degree of self-anti-interference ability in the Absence of noise.
