In my program, I have a 2D binary array, which represents an image. I then compare my binary array to other binary arrays, to find the most similar image.

But, I have an issue with orientation. In order for a comparison to be made, they must all be oriented the same way (i.e. longest part of the image along the x axis). How would I go about finding the longest line of the shape and then orienting that along the x axis?

That sounds like a PCA problem. https://github.com/mkobos/pca_transform – DejaVuSansMono Dec 15 '16 at 20:49
