Figure 6

The origin of the two red lines has a ψ angle with degree m, corresponding to the red, mth, bin which contains two (r, α) pairs. Solid lines denote correct matches, while dashed lines represent noise. Different points on the head-shoulder contour in the edge image converge to a local maximum on the detection map on the right. At the bottom is the 180-bin reference table; a Gaussian weighting g is shown below the table, with the center bin labeled in red and the neighboring ten bins in blue.
