I would like to know why the size of the HOG vector is the same for each image with different sizes.

Hi, I have one question.
I want to use HOG with SVM. Your code returned different size's of vector's for different images. But, to train the features with SVM, the vector's must be in the same size.
How can I solve this problem?
Sorry for my bad english, I'm Brazilian.

I have the same problem of Chun-Yi. When I try to run your code with another trained classifier, I have the error :"Warning: Tilted features are not supported "
And there is no results.
How I can solve the problem?
