Band detection within a lane. (A) The image of a lane with three bands, two of which migrated as a doublet, and some minor artifacts. (B) The blue curve is the summed pixel intensities of a lane and the green stems are possible band locations detected as the first order derivatives. (C) The three green stems are genuine band locations that pass the background threshold (red line).
