Abstract
This paper presents a new method for edge detection by combining the Sobel operator and the Laplacian of Gaussian (LoG) operator. The underlying idea is to combine the advantages of both operators and eliminate their disadvantages. Different methods of combining the two operators are considered. One method yields promising results in precise and blur free edge detection, and good stability versus image noise. A method for designing the LoG kernel is also presented.
