 Edge Detection is an important task for sharpening the boundary of images to detect the region of interest. This paper applies a linear cellular automata rules and a Mamdani Fuzzy inference model for edge detection in both monochromatic and the RGB images. In the uniform cellular automata a transition matrix has been developed for edge detection. The Results have been compared to the ...

In this paper, an improved DWT based edge detection algorithm for noisy images has been proposed. The proposed edge detection method works efficiently on images influenced by noise and is able to differentiate between noise and real edges, thus detecting the actual edges. In the proposed algorithm the DWT edge detector separates detail coefficients at the time of decomposition, thus it has to e...

A modified ant-based edge detector is presented. It is based on the distribution of ants on an image. Ants try to find possible edges by using a heuristic function based on 3x3 ideal edge structures. Visual comparisons show that the modified algorithm gives finer details and thinner edges at lesser computational times when compared to earlier ant-based approaches. When compared to standard edge...
