Abstract:

Scenes consisting of spatially compact regions which contrast with their surrounds can be segmented by extracting connected components of above-threshold values whose borders match the positions of edges. Edgeborder coincidence thus defines a kind of optimal thresholding, since for any object we can choose the threshold which maximizes the coincidence. This illustrates how the redundancy of different information sources aids segmentation. Author
