With the end goal of segmenting a picture of a building into as many coherent features as possible, reflections on our current use of the probabilistic flavour of the Hough Lines Transform lead to a sense of the division not being exactly what we were after.

Despite being a faster algorithm, it leaves the lines un-interpolated, meaning that some features are not fulled enclosed in the lines:

unenclosed lines

Upon performing the standard Hough Lines Transform however, we can see the lines are nicely interpolated, meaning a more thorough segmentation of the image in general and furthermore, its features:
