WebJan 4, 2024 · This representation is used in OpenCV). So Any line can be represented in these two terms, (r, θ). Working of Houghline method: First it creates a 2D array or accumulator (to hold values of two parameters) and it is set to zero initially. Let rows denote the r and columns denote the (θ)theta. Size of array depends on the accuracy you need.
