ihough - Inverse hough transform
Calling Sequence
- im = ihough(ht,dims)
Input Parameters
-
ht:
binarized Hough transform accumulation matrix. Rho varies along rows; theta varies along columns. Theta range is 0-179 degrees w/ 180 samples.
-
dims:
vector with the size of the output image. Can be the output of the size routine.
Output Parameters
-
im:
binary image with digital straight lines
Description
Function ihough calculates the inverse hough transform of a binary image. It takes as input a binarized hough image, and draws the corresponding digital straight lines in the output image.
Examples
Cf. help page for hough.
