Hi,

I am trying to detect whether or not a logo exists in a screenshot, outputting a boolean variable. Template matching is not a suitable solution for me since the logos are not exactly the same (obtained from different sources with different resolutions etc). I thought I could use feature matching however this has over matched each logo on each screenshot, providing the same number of matches for a logo on the page vs a logo not on the page. I also tried matching with FLANN but got 0 matches. Results are as follows:

AT&T logo in AT&T page (basic feature matching) C:\fakepath\image0.png

PayPal logo in AT&T page (basic feature matching) C:\fakepath\image1.png

AT&T logo in AT&T page (FLANN feature matching) C:\fakepath\image240.png

AT&T logo in AT&T page (object detection) C:\fakepath\image3.png

Any ideas of what I can try next?

Thanks
