•Construct an
array representing m, b
•For each
point, render the line
y=mx+b into this array,
adding one at each
cell
•Questions
–how big should the cells be?
(too big, and we cannot
distinguish between quite different lines; too small, and noise causes lines to be missed)
•How many
lines?
–count the peaks in the Hough
array
•Who belongs
to which line?
–tag the
votes
•Can modify
voting, peak finding to
reflect noise.
•Big problem if noise in Hough
space different from noise
in image space.
