Analysis: initialize class with raw images?

[hillierdani]

Hi, In you very nice and clean code I miss one bit: given the raw series of camera images how should I initialize the analysis class? In your code you seem to import already preprocessed data. Thanks!

This is right. Because of the various hardware and software that people are using for acquiring images, there is no universal way to preprocess data. I assume all the preprocessing will converge to an intermediate stage that is universal. That is an azimuth map and an altitude map of cortex (ideally also a vasculature map), all in same size. My jupyter notebook example starts from there, calculating the visual sign map and segmenting the sign map into several patches (putative visual areas).

I have updated the example notebook to describe the preprocessing steps to generate altitude map and azimuth map.
