Hello all,

I'm doing a project on heterogeneous face recognition. The work flow of the project is Feature Extraction (SURF and SIFT descriptors) and appying KNN Classifier. I'm using matlab for implementation. The extacted feature values are summed up for each image and classified using KNN. Result of Knn classifier is class label. But all projects in this domain have used CMC Curve for accuracy i.e (Recognition rate versus Rank). So how to obtain similarity score of test image to every class or data for CMC Curve??

Thanks in advance........
