feat: cDNA微阵列图像处理作业 - Python实现
实现内容: - 网格划分:投影分析 + 自相关估周期 + 白顶帽去背景 + 质心提取 - 三种阈值分割:人工阈值、Otsu自动阈值、迭代阈值 - TV去噪(Chambolle投影算法) - 后处理:去小连通域 + 保留最大连通域 - 完整可视化:网格叠加、阈值对比、收敛曲线、分割结果 参考MATLAB代码:NewGridAndCV/demo_GriddingAndCV.m

function [x,y]=limits(a)
|

% LIMITS returns min & max values of matrix; else scalar value.
|

%
|
||||
% [lo,hi]=LIMITS(a) returns LOw and HIgh values respectively.
|
||||
%
|
||||
% lim=LIMITS(a) returns 1x2 result, where lim = [lo hi] values
