视差梯度 meaning in English

gradient of disparity

At last , quick edge matching method based on the two constraint was given
最后给出了基于视差梯度约束和边缘幅角约束的快速边缘匹配算法。
On the basis of the probability density function of the disparity gradient , the mutual coordinate constraint of the corresponding points of the two adjoing points in the continous edge of the left image was educed , then the search area of the matching point in the right image was limited
由视差梯度的分布密度函数，导出了左图像连续边缘上相邻两点在右图像中的对应点的坐标间的相互约束关系，从而限定了右图像中匹配点的搜索范围。
