A line in Cartesian form has the equation: Given a set of edge points or a binary image indicating edges, we want to find as many lines that connect these points in image space. Say we have 2 edge points (x1,y1) and (x2,y2). For each edge point at various gradient values (m=-0.5, 1.0, 1.5, etc), we calculate the … See more A line in the Polar coordinate system has the equation: If you’re interested in how ρ is derived, I’ve laid out the maths at the bottom of this post.
