Abstract
Two techniques for extracting foreground edges from an edge map are quantitatively tested and compared. Although Amir and Lindenbaum’s algorithm (Comput. Vision and Image Understanding 76 (1) (1999) 7) and Venkatesh and Rosin’s algorithm (Comput. Vision Graphics Image Process. 57 (2) (1995) 146) operate on very different principles it is shown that their results or of similar quality. The advantage of Venkatesh and Rosin’s algorithm is that it is computationally more efficient and does not require tuning parameters.
