So I am implementing The Maximum Response (MR) Filter Bank - MR8.
I am using this as a reference:
<http://www.robots.ox.ac.uk/~vgg/research/texclass/filters.html>

And so far I have written the 38 filters, but have no idea how to compute the maximum filter response from the 6 rotations of each edge and bar filter variations.

1. What is a filter response?
Is it the result from the filter application or something else?
2. What is a maximum response?
3. How to compute the maximum responses for the edge and bar filters?
