Dear Experts,,
I am working on people detection using HOG method. However I have a problem on visualization the HOG features in MatLab. I know there is a function provided by MatLab to extract the HOG feature, but I would like to know how to write the code for the visualization of HOG feature in MatLab. Anybody has idea to help me on this problem?
Thank you.

suppose you have an image called "image01.jpg"
img = imread('image01.jpg');
[featureVector,hogVisualization] = extractHOGFeatures(img);
% featureVector is HOG features
% hogVisualization is HOG feature visualization
you can display the result of HOG features with
plot(hogVisualization);
