摘要：This paper is about a algorithm used for edge detection using logical operations. First image is converted into binary image and then it is rotated left, right, up and down. Afterwards logical AND operation is performed between rotated and original image and results are stored in different variables. After that XOR operation is performed between the results that are stored and then OR operation is performed on all results obtained after XOR operation. These operations are repeated for different values of threshold to get the final result constituting of only edges of that image. This method gives better or comparable output as given by other edge detection algorithms. This algorithm can be applied to variety of colored images
