Hi, i need some help in finding the dimension of lines. After i detect two lines using Hough Transform, i wanna do further processing, for example calculating the lines is parallel or not. So, first, i need the dimension of the two lines, can anyone help me. Thank you

What do you exactly mean by dimensions? Length? Slope?

Do you mean you want the pixel indices? i.e. addresses of the lines in the image which you can then use to determine other parameters?
