i have an android project to recognize leaf image. I have been using invariant moments to extract the shape feature of leaf, and using City Block Distance for matching. I want to use another feature extraction and matching method in opencv to recognize the leaf. So, what feature extraction and matching method should i use?

  • Do you mean local image features? Empirically I think they will not work very well to recognize leafs but you can always try it yourself and measure the accuracy for your data. You can start by ORB. – Rui Marques Feb 15 '14 at 22:48
  • @RuiMarques thanks for the response, now i'm in project of using ORB, but i confused about to store the feature data. Anytime i input the image, the keypoint of the image always different. Can i store the feature to database? or must i store the image (as data to store the feature)? – gussurya_w Feb 18 '14 at 08:51
  • You can store the features but maybe you should create a new question with that topic. – Rui Marques Feb 18 '14 at 09:37

  • Hi. Fortunately I'm doing a project related to image processing and I'm in the feature extraction phase, please can you let me know the resources you've used and what featured you've extracted to detect the leaf? – Shankar Feb 05 '16 at 09:41
