2012-09-13 00:36:11 -0600 | asked a question | Find image inside of another (corners detection?) Hello. I want to write a function that checks if one large image (screenshot of the whole screen, for example 1920x1200) contains specified small image (from 32x32 to 300x300). And I want that it works fast, not more than 1 second (system requirements is something like Athlon II X3 3GHz + GTS250). I've read that one of the ways to do this is to use corners detection. How should I start? Can't find any tutorial about that. I am using C# and EmguCv but I think C++ example also would be great. |
