Boundary Detection Benchmarking: Beyond F-Measures

Xiaodi Hou, Alan Yuille, Christof Koch
2013 2013 IEEE Conference on Computer Vision and Pattern Recognition  
Then we analyze the computation of f-measure and point out that the current benchmarking protocol encourages an algorithm to bias towards those problematic "weak" boundary labels.  ...  Compared with the active research on finding a better boundary detector to refresh the performance record, there is surprisingly little discussion on the boundary detection benchmark itself.  ...  The list of boundary detection algorithms referred in this paper. Their F-measures increase over time.  ...
