I write a code that detect people in crowed and I tray to use SURF , MSERF and HOG Features my quistion how can i combine this features ???
points1 = detectSURFFeatures(grayI)
[feature, valid_points] = extractFeatures(grayI, points1);
[regions,dd] = detectMSERFeatures(grayI);
[features2, valid_points] = extractFeatures(grayI,regions);
[featureVector,hogVisualization] = extractHOGFeatures(grayI);

To get the combined feature vector use
combinedVector = [feature( : ), features2 ( : ), featureVector( : )];

It is because features extracted are of different length. Check for the lengths of each feature vector and pad accordingly to combine them. I would suggest you to go through the following link that combines matrices of different sizes.
Hope this helps.
