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.

see https://www.mathworks.com/help/vision/ref/extracthogfeatures.html#inputarg_I
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);
