How hough function of matlab works?

i have read the working of hough function from the mathworks, but i am not able to understand how the function consider the THETA value and the RHO value in order to calculate the HOUGH matrix, that is i am not able to know how the orientation of THETA are consider.

Hi Roma,

I understand that you are looking for more insights on how the values of THETA and RHO are defined to calculate the HOUGH matrix. Here is an explanation:

• RHO represents the perpendicular distance from the origin to the line.
• THETA is the angle of the perpendicular projection from the origin to the line in degrees, measured in a clockwise orientation from the positive x-axis.

For more information, refer to the ‘Algorithms’ section of the “hough” function in the following MATLAB documentation link: https://www.mathworks.com/help/releases/R2024a/images/ref/hough.html#buwgokq-6
