I am working on a survey between feature descriptors, so does anyone know how I can find HOG or GLOH implementation in matlab.
There are lot of codes available for HOG. You can search in google you will get it.
There is one such code available at
http://www.mathworks.in/matlabcentral/fileexchange/28689-hog-descriptor-for-matlab
I found alot of code but it is not working good like sift code , i want use in search
HOG and its feature enhancement like PHOG, CVOG, etc can be easy implemented from the alogirthms given in the respective papers. It is not difficult. One feature which may give good search result for one type of object may not work for other type of objects. Please also see PASCAL VOC (Visual object challenge), which is an international challenge with only 20 diffierent objects and also see the results of different features.
hi,@Reghunadhan Rajesh I use this code for an matrix , then I do reshape and extract features and then reshape again for convert vector hog to matrix but in this convert I lose half rows of matrix please help me
A one question is that I problem in extract features because of I cant determine edge of the object

study these links so that HOG understand
Dear Farzana Alam ,
Please find the link below regarding HOG features extraction in python:
http://scikit-image.org/docs/dev/auto_examples/features_detection/plot_hog.html
You can use this
features = extractHOGFeatures(I), all details can be found in the link below
