Multi-object contours extraction has been widely used in image processing and graphic drawing. Piece-wise constant methods which are based on binary value images are not suitable to piecewise smooth images. An improved level set method is presented for piecewise smooth multi-object area contours extraction. Firstly, the disadvantages and limitations of currently used conventional model are pointed...
Median value filter is used to eliminate or reduce the noise caused by the outside environment. The edge information of road image is enhanced by Sobel operator. And then based on the Otsu method, an effective algorithm is proposed to binary-code the lane image in order to segment and identify road edge easily. Finally, Hough transformation is used to extract the feature of lane and detect the lane...
