2013-10-24 04:50:14 -0600 | asked a question | Feature couldn't be extracted from some gif images using Flannbased matcher I was just trying to compare two images by feature point matching using SIFT. I am using SURF type Descriptor Extractor to do this. Now for some GIF images the descriptor extractor returns empty. Why & What to to in this case? |

2013-10-24 04:44:14 -0600 | answered a question | OpenCV error unsupported format or comibation of formats when doing FlannBased matching This problem occurred when the descriptors could not be found from a image. Means the features couldn't be extracted from images for various reasons. Just check the descriptors for empty. Surodip |

Whatever I have found from internet searching that SIFT is a good way to do that. I have extracted features and find the matches. Now I have the MatOfDMatch. I want to calculate the percentage of similarity from it. Can anyone help me in this? Below is my code: Thanks, Surodip |
