Image recognition (shape recognition)

Question

I want to recognize the shapes in the picture using pattern matching. For this purpose, the "Exhaustive template selection" option is used, which is given in Aforge.Net for this purpose. Someone tried this class and found that it works correctly. As an accurate and correct choice, this class is intended to achieve my goal. Follow any other methods or Alograms, as well as for pattern recognition by pattern matching. For example, the identification of the ComboBox in the picture.

Answer 1

OpenCV MatchTemplate works very well, especially after you run edge detection (e.g. Canny) on the source and template. You can also look at SURF (Accelerated Reliable Features).
