A Hybrid Edge Detection Method for Cell Images Based on Fuzzy Entropy and the Canny Operator
نویسندگان
چکیده
Since cell biologists need to use image processing techniques, such as edge detection, to analyze cell images the precision of these techniques is pivotal to their work. Due to the often low quality of cell images, existing edge detectors fail to routinely produce highly accurate results. In this paper, a novel hybrid method based on the canny operator and fuzzy entropy theory is proposed. The method calculates the fuzzy entropy of gradients from an image to decide the threshold for the canny operator. Application of the method to cell images has demonstrated its excellent performance in edge detection and robustness in the presence of noise.

In this paper, a new algorithm for edge detection based on fuzzyconcept is suggested. The proposed approach defines dynamic membershipfunctions for different groups of pixels in a 3 by 3 neighborhood of the centralpixel. Then, fuzzy distance and -cut theory are applied to detect the edgemap by following a simple heuristic thresholding rule to produce a thin edgeimage. A large number of experime...
