摘　　要：为了解决计算机识别2帧图像是否属于连续形变问题,提出了一种新的算法:利用压线格分别提取2帧图像的边缘信息,以2帧图像压线格重心坐标的位移量作为判断图像发生形变的依据.具体如下:首先计算出第2帧图像中发生突变的压线格的数量;再用发生突变的压线格的数量与第1帧图像的方格数相比,如果比值小于或等于程序中设定的阈值,则此两帧图像属于连续形变,否则,属于非连续形变.In order to find out whether two frames of images belong to continuous deformaton,a new algorithm is put forward to get edge-information of the image by using so-called line-grid. It is based on two images′continuous deformation on the distance variant of their line-grids′gravitational center. The concrete way is introduced as following :first, calculate the numbers of the line-grid in sharp changes; second, use the numbers obtained in former step to divide the numbers from the first image′s numbers of grids; finally, use the quotient obtained to compare with the threshold set in algorithm. If the quotient is smaller than or equal to the threshold, the two images are proved to be within continuous deformation;otherwise within discontinuous deformation.
