    本程序主要实现暗背景下含高斯噪声的光斑滤除噪声,实现光斑中心提取。采用了sobel算子和梯度倒数加权滤噪、最大类间方差法(Otsu)确定阈值、质心法提取光斑中心坐标。(The program is mainly realized under a dark background Gaussian noise spot containing noise filtering, to achieve spot center extraction. Using sobel operator and gradient inverse weighting filter noise, Otsu method (Otsu) to determine the threshold, the center coordinates of the spot centroid extraction.)

  • Matlab 的采样
    图像的采样 • 写程序:以2 为尺度,下采样图像 ,观察不同分辨率下图像的变化情况(a) • 写程序:把(a)中获得的图像,进行上采样处理,可以选择不同的平滑方 法,比如,邻近像素复制,或者线性插值等。讨论上采样后图像的质量变 化。找出相应的改进方法。
