Junction Detection

Recently I have been focusing on detection of junctions and end points on a raster network. It is suprisingly difficult, but I have something that works nicely on test images.

The parameters the algorithm uses seem to be quite sensitive at the moment, this mainly due to the point grouping function. I need to come up with a more stable point grouper…

However, with the junction detector working vectorising a network is simple a case of line following out of one junction until reaching another!
