Extracting information from an object into variables?
显示 更早的评论
Hey guys, I'm fairly new to MATLAB and I wrote the code to detect eyes in an image. I'm using:
corners = detectFASTFeatures(sobel, 'MinContrast', 0.05);
and I need to get the coordinates of the eyes in variables left_x, left_y, right_x and right_y. How should I go about this?
Thanks for reading!

I assume this returns an object of some ilk, though I do not have the necessary toolbox to verify that assertion.
When you don't know how to work with an object of some class, I would first read any help on that class I could find. Surely you will find some.
If you get nowhere on that front however, there are a few tricks to try. The first one I would look to is:
methods(corners)
See what it tells you. What functions are defined? Is there anything that looks useful?
If that fails to prove helpful, try this:
S = struct(corners)
This will extract the information stuffed into the object, into a structure. Do any of those fields seem like they have useful information inside them?
