between image (x,y) and Hough (m,b) spaces |
||||||||||
| � | A line in the
image corresponds to a point in Hough space |
|||||||||
| � | To go from image
space to Hough space: |
|||||||||
| � | given a set of
points (x,y), find all (m,b) such that y = mx + b |
|||||||||
| � | What does a point
(x0, y0) in the image space map to? |

|
|
| � | A:� the solutions of b = -x0m + y0 |
||
| � | this is a line in
Hough space |
