| 摘 要： | 提出基于像素块的边缘直线检测算法.先在取定的像素块中建立模板,在原图上移动像素块并用模板进行比对,对累加变量进行累加,而后用阈值判定法则进行判断,最终确定出边缘直线段.通过编程试验证明了其算法的有效性.

| Abstract: | A novel edge detection method based on blocks of pixels is proposed to detect edge line of images.A model matrix is set up in the selected pixel block.The block is moved through the image,and the correlation values are accumulated.Then,it is judged whether the line is straight or not.Programming experiment has proved the validity of the algorithm. |
