I have Image retrieval system , i have extracted the features, and testing , training is performed by Multisvm, I obtained Confusion matrix for that... but how to obtain the precision and recall plz help.
You have the confusion matrix so that gives you everything you need. What more do you want? How are you defining precision? Is it (# true positives) / (number of images)? Well, you can get that,plus more, from the confusion matrix. Please explain why the confusion matrix is not giving you everything you want.
