Hough Algorithm: So far we have seen…..
- Choose an analytic form f(x,y,a1,a2,…,an) and choose a range of values for parameters a1, a2, a3,….,an.
- Create accumulator array A(a1,a2,…,an) which represents direct match of f(x,y,a1,a2,…,an) with binary image.
- Local for local maximum which exceeds certain threshold.
