Cue detection with steerable filters
Corner (green), T (red), and X (green) junction detection
Outputs of L, T, and X junction detectors
The outputs of L, T, and X junction detectors are overlaid on these
simple test images in green, red, and blue, respectively. The
junctions are correctly detected, independent of whether the contours
forming the junctions are formed by lines or edges.
