本文以提取靶标圆心像坐标为主要研究目标。用到了灰度处理、图像二值化、八邻域连通法、最小二乘法、无约束最优化等知识。 -In this paper, to extract the target coordinates of the center as the main research objectives. Use the gray processing, image binarization, the eight-neighbor connectivity method, least sq

提取指纹特征点的matlab代码，很有用，利用自适应阈值进行分割，再进行频域增强，根据八邻域纹线编码进行特征提取。-Extracted fingerprint feature points of the matlab code, useful, adaptive threshold segmentation, and then increased in frequency domain, the eight neighborhood ridge coding for feature extrac

八邻域实现的连通域标记，可以去除小的区域-Achieve eight neighborhood connected component labeling, you can remove some of the small non-candidate region

八邻域激光点搜索,可用于激光点的寻找-Eight neighborhood of the laser spot search can be used to find the laser spot。。。
