Hi, I’m trying to find multiple instances of similar object in one picture.
Object is this black ring on light background. So far, I was able to find it with:
-template matching, with results differing from images and templates used (as expected)
-using inRange() color filter for image in HSV and RGB color space, with fairly good results,
-Haar/LBP Cascades that work remarkably well,
I wanted to do it using Feature Matching, but I can’t get it to work properly. Depending on used detector, it detects features inside and in neighbourhood of the object, but it cannot match template with objects properly. Template is square image of black ring on light background, cut from pictures. Could it be because object is “too simple”? I use high resolution pictures (~12Mpixels), could that be a problem?
Also, I wanted to ask, what are other methods that I could check for this application.
