Embodiment Construction
[0056] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0057]Since the second-order differential component contains richer information, the present invention uses the level set curvature in morphology as a local feature representing the image, and provides an image curvature smoothing method. After observing the smoothed image processing results, it is found that when the image When being polluted by noise, the curvature will change significantly, so the present invention further substitutes the level set curvature of the image into the PM method as a detection factor, establishes an image smoothing method combining gradient and curvature, and finally uses MATLAB software to carry out the method Simulations, denoised ...
