使用opencv在iPhone中进行图像匹配/检测 [英] image matching/detection in iphone using opencv

问题描述

我有2张图片，例如bigImage和smallImage.我想检测smallImage是否在bigImage中的任何位置，而不论其方向或transforms(rotations).如果存在，则应返回true，否则返回false.我已经经历过openCV中的模板匹配(cvMatchTemplate)方法，但是由于对与错匹配的输出之间没有太大差异，因此没有到达任何地方.使用cvMatchTemplate是否仍然可以满足我的要求，或者在openCV中还有其他方法可以做到这一点.

I have 2 images, say bigImage and smallImage. I want to detect whether the smallImage is there anywhere in the bigImage, irrespective of its orientation or transforms(rotations). If its there, it should return true and otherwise return false. I have been going through the template matching (cvMatchTemplate) method in openCV, but haven't reach anywhere since there aren't much difference between the output for a true and a false match. Is my requirement still possible using cvMatchTemplate or are there any other methods in openCV for getting to this.

推荐答案

这是一个非常普遍且非常棘手的问题，有很多解决方案.它们都不是银弹.希望其中之一将为您解决特定问题.尝试看一下SIFT，颜色直方图匹配，SURF，HoG，Viola-Jones，DOT和ORB.其中一些具有OpenCV实现；其他人没有.您应该阅读可用的选项以及它们的优缺点，然后尝试一下.

This is a very general and very hard problem, with lots of solutions out there. None of them are silver bullets; hopefully, one of them will work for your particular problem. Try taking a look at SIFT, color histogram matching, SURF, HoG, Viola-Jones, DOT, ORB. Some of these have OpenCV implementations; others don't. You should read up on the available options and their strengths and weaknesses, and then try some out.
