This situation relates to the way HOG is implemented! So, you should provide your code to be investigated in details.

Jamal Gardezi

May be the output is not stored properly ,or the image input matrix is not given properly and is empty.

Wen Su

First, I think there is something wrong with your codes. Are you sure your codes are correct?

Second, there maybe any data type problems. The data is too small to be stored correctly and vice versa. you can check your middle process.

Hope can help you.

Muhammad Haggag

you said, "I get empty matrix for some windows".

That can happen for blank patches (ie, filled with the same color), then image gradients will be zero.
