How do you use Hough transform to detect lines?
Create a hough transform matrix using the hough function. Locate the peaks in the Hough transform matrix function. The peaks correspond to the intersection point in the parameter plane. Each of these peaks is a detected line.
How does Hough line detection work?
If two edge points lay on the same line, their corresponding cosine curves will intersect each other on a specific (ρ, θ) pair. Thus, the Hough Transform algorithm detects lines by finding the (ρ, θ) pairs that have a number of intersections larger than a certain threshold.
How can I identify lines in an image?
In image processing, line detection is an algorithm that takes a collection of n edge points and finds all the lines on which these edge points lie. The most popular line detectors are the Hough transform and convolution-based techniques.
