Matlab-vision包学习-Feature Detection,Extraction and Matching-FAST角点检测
来源:互联网 发布:西门子plc300编程软件 编辑:程序博客网 时间:2024/05/27 19:25
这一篇主要介绍vision包中的FAST角点检测算子。
函数/Functions
函数名称:detectFASTFeatures
功能:利用 Features from Accelerated Segment Test(FAST)算法检测特征点,返回检测到的特征点
语法:points = detectFASTFeatures(I);
points = detectFASFeatures(I,Name,Value);
其中,I为2-D灰度图像,points为返回的FAST检测到的特征点,Name必须为用单引号对包含的如下字符串名称,Vaule为对应Name的值
举例:
Img = imread('cameraman.tif'); corners = detectFASTFeatures(I); imshow(I); hold on; plot(corners.selectStrongest(50));
