| 摘 要： | 结合Laplacian算子与灰色关联度提出了一种新的图像分割技术,即以Laplacian变形算子作为参考序列,计算每个像素点及其8-领域的灰色关联度,从而辨别该点是边缘点还是非边缘点.实验结果证明,该方法可以有效地提取图像边缘,而且可以通过调整关联度的阈值和分辨系数来控制边缘信息量.

| Abstract: | A new kind of image division technology by combining Laplacian operator and the degree of gray relation is proposed,which takes the transformative Laplacian operator as reference series. The degree of relation of each pixel and its 8-adjacency is calculated to decide whether the pixel is the edge point or not.Through the experiment,this method has received a good effect in image edge detection.Moreover edge information content by adjusting the threshold of degree of relation can be controlled. |
