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( : )];

I have got this error
"Dimensions of arrays being concatenated are not consistent"

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.
