More Information
Summary:The invention firstly provides an image curvature smoothing method, and the method takes the image level set curvature as the second order micro component for describing the image morphological feature and improving the image processing effect. The curvature obviously changes while the image is polluted by the noise, the method further takes the image level set curvature as the detection factor to be applied to the PM method, the image smoothing method with combination of gradient and curvature is provided, and the method can keep the feature of the image, the peak value signal to noise ratio is greatly improved compared with the previous anisotropy method, the complexity is low, the timeliness is high, the image resolution is improved, the method has more effectiveness and veracity compared with the previous image smoothing method, and the image processing effect is better.
