Hello Ahmed, can you share the code (combination of SURF features and HOG features) to my email chidosky4ril@yahoo.com. Thank you

Hi Ahmed,
It would help if you could tell us more about what you are trying to do.
The extractHOGFeatures function in the Computer Vision System Toolbox has two different modes. The most common mode is to compute a single HOG descriptor for the entire image. The second mode is to compute multiple HOG descriptors centered around a given set of image points, similar to what extractFeatures does for SURF or FREAK descriptors.
As to how to combine SURF and HOG, that depends on what it is you are trying to do. If you are using the bag-of-features approach for image classification, you may want to concatenate the bag-of-features histogram with a HOG vector computed over the entire image. If you want to match features, you can try concatenating individual SURF descriptors with HOG descriptors. Or you can extract SURF descriptors from one set of points, and HOG descriptors from another.

Thanks Dima Lisin for your answer I want to extract HOG features for image classification using bag-of features. How can make the concatenation between the queries HOG feature vector and database HOG feature vector

how to combine SURF and HOG
here is the simple solution as per my knowledge and i have used also
surf = [surf_features];
HOG = [hog_features];;
combined_Features = [surf_features,hog_features];
now you have the simple concatenated feature set.
hope this will help you.
