Computer vision functions to locate largest square or rectangle inscribed inside arbitrary shape

| Watch this File

File Information

Inscribed_Rectangle package provides 2 low level computer vision / image analysis functions able to locate largest square or rectangle inscribed inside arbitrary shape defined by a binary mask (black and white image). Only rectangles with vertical/horizontal edges are considered. The functions proved can be used as tools for larger image segmentation problems

The code produces an incorrect result if the input is an entirely white image. Changing line 25 of FindLargestRectangles.m into "if max(I(:)) == 1" appears to solve this problem.

No, in the the problems I was working on the rectangles are always parallel to the edges.

Can it find tilted rectangles, not aligned with the image edges?
