Detecting rectangle using Hough Transform in real road images
25 views (last 30 days)
I wanna detect road sign based on shape detection
so what I need to do first is detecting rectangle.
I extracted line segments from original image using Hough Transform, and I attached example.
As u can see, every single line(different color) contains 4 values, which means 2 points.
My problem is the lines are incomplete to be rectangle, cuz it's not connected.
Anyone has ideas to solve it???
Thx in advance!
