Figure 6-8 show the result of performing edge detection on the arm image and introducing a measure of significance by integrating the measure of edge strength along each connected edge curve. As can be seen, coarse scales are selected for the diffuse edge structures due to illumination effects, whereas fine scales are selected for the sharp edges due to object boundaries. Notably, the selected scale levels vary substantially along the shadow of the arm, which is necessary to obtain a good trade-off in the inherent conflict between detection and localization properties.
