Draw in either canvas to see the transform in the other canvas.
• Image Space: Points and lines in Cartesian coordinates (x,y)
• ρ-θ Space: Lines represented in polar coordinates as ρ = x·cos(θ) + y·sin(θ)
• m-c Space: Lines represented in slope-intercept form as y = mx + c
• Use the "Detect Lines" button to find lines in the image based on peaks in the Hough space
