Figure 9.40 Test image of bicycle after Canny edge detection.
This image has been significantly resized to match the economy image. I applied the
outline edge detector first, as I had done in the first test. Figure 9.43 is the result of this
outline-edge-detector post processing. This time you can easily see the tire outlines and even
the outlines of the handlebar and seat—a definite improvement over the previous outline
edge test.
