Considering that the non-destructive testing(NDT)image is easy to be disturbed by noise and the target occupies a small area of the image, a robust and adaptive suppressed fuzzy C-means algorithm based on the image patch(SFCMP)is proposed to segment NDT image. Firstly, the weight of the pixels in the image patch is adaptively determined, which is affected by the spatial distance and gray value of each pixel in the image patch. Then the fuzzy uncertainty model of image patch is constructed, and it is introduced into the new objective function with image patch as the basic unit, and the implementation process of the SFCMP is given. Finally, experiments are carried out on the NDT images, and the results show that the SFCMP has good robustness and effectiveness.
