Get HOG image features from OpenCV + Python?

Question

I\'ve read this post about how to use OpenCV\'s HOG-based pedestrian detector: How can I detect and track people using OpenCV?

I want to use HOG for detecting othe

Answer 1

I would not recommend using HOG features for detecting objects other than pedestrians. In the original HOG paper by Dalal and Triggs, they specifically mentioned that their detector is built around pedestrian detection in allowing for significant degrees of freedom in the limbs while using strong structural hints around human body.

Instead, try looking at OpenCV's HaarDetectObjects. You can learn how to train your own cascades here.
