通过对选定图像在屏幕上的差值计算来获取图像运动的方向，距离等数据。-Through the selected image on the screen to get the difference between the calculated movement direction of the image and distance data.

对图像上的一组平行线段根据距离，角度，截距进行分组过滤，统计-The image of a group of parallel lines according to the distance, angle, intercept packet filtering, statistics

由于纹理是由灰度分布在空间位置上反复出现而形成的，因而在图像空间中相隔某距离的两象素之间会存在一定的灰度关系，即图像中灰度的空间相关特性。灰度共生矩阵就是一种通过研究灰度的空间相关特性来描述纹理的常用方法。 Gray-level co-occurrence matrix from an image 图像的灰度共生矩阵(Because the texture is formed by the repeated appearance of the gray distribution in the
