Name

ihough — Inverse hough transform

Calling Sequence

im = ihough(ht,dims)

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.

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.
