%X Edge is one of the most fundamental features.Edge detection is an important method to extract the image's characteristics.Firstly gradient adjusted predictor is used to predict the image,and then aiming at the gained error image,a new adapted approach to selected threshold based on gradient mean-value histogram is proposed,and classified edge and non-edge by the gained threshold;to obtain single pixel edges,the gained edge image is far thinned by the thinning algorithm,and the last edge image is achieved.Si...
