Segmenting Multiple Objects with Overlapping Appearance and Uncertainty
2006
Procedings of the British Machine Vision Conference 2006
Preserved Fulltext
A probabilistic method is proposed for segmentation of multiple objects that overlap or are in close proximity to one another. ...
A likelihood function is formulated that explicitly models overlapping object appearance. Priors on global appearance and geometry (including shape) are learned from example images. ...
Multiple Object Appearance When segmenting multiple objects, appearance overlap should be taken into account. ...

Instance segmentation of overlapping objects in biomedical images remains a largely unsolved problem. ...
The key novelty of our method is that we identify pixels at which objects overlap and use this information to improve proposal sampling and to avoid suppressing proposals of truly overlapping objects. ...
Many applications require segmentation of the full overlapping objects, which means that multiple instance labels need to be assigned to pixels in the object overlap. ...
