Contour Detection Model Based on Mechanisms of Visual Perception in Environment of Low Contrast

The traditional contour detection model based on mechanisms of visual perception loses some of the object contours at low local contrast. And it augments the noise or breaks around the corner of the local high curvature contour in the collinear enhancement. To solve these problems,a contour detection model based on the mechanism of visual perception in the environment of low contrast is proposed. Based on the traditional model,the adjustment...
