I think you have to follow below procedure: 1) take input image 2) Preprocessing 3)Segmentation 4) Feature extraction 5) save features in database (you can use .mat format to save extracted features)

Hi @Sudhakar Shinde... Can you please tell me how to save features in database.

   %%Extract the MSERF Features
        [features2, valid_points1] = extractFeatures(im1, points1);
        figure; imshow(im1); hold on;      
plot(valid_points1.selectStrongest(10),'showOrientation',true);
feature = binaryFeatures(im2uint8(features2)).
