Abstract
The effect of existing methods for image edge detection is not ideal,and the detected image edge may be fuzzy.Therefore,combining fractional-order differentiation theory with the existing Laplacian operator method,a new image edge detection model based on fractional-order differentiation was proposed.Compared with the existing integer-order differentiation edge detection methods,the experimental results show that the model,not only can detect the image edge well,but also have a certain effect on noise.It can detect more texture detail information especially for texture rich images.It is an effective method for edge detection.
