摘要：To segment an image in thresholding method, a fixed threshold is not suitable if the background is rough here, we propose a new robust adaptive thresholding method using TKFCM. The method requires only one parameter to be selected and the adaptive threshold surface can be found automatically from the original image. A Robust adaptive thresholding scheme using adaptive tracking and morphological filtering. TKFCM algorithm computes the fuzzy membership values for each pixel. On the source of TKFCM the edge indicator function was redefined. Using the edge indicator function of an image was performed to extract the boundaries of objects on the origin of the pre-segmentation. Therefore, the proposed method is computationally efficient. The efficiency and accuracy of the algorithm is demonstrated. The above process of segmentation showed a considerable improvement in the evolution of the level set function. Our method is good for detecting large and small images concurrently. It is also efficient to denoise and enhance the responses of images with low local contrast can be detected.
