BiSeg: Simultaneous Instance Segmentation and Semantic Segmentation with Fully Convolutional Networks
We present a simple and effective framework for simultaneous semantic
segmentation and instance segmentation with Fully Convolutional Networks
(FCNs). The method, called BiSeg, predicts instance segmentation as a posterior
in Bayesian inference, where semantic segmentation is used as a prior. We
extend the idea of position-sensitive score maps used in recent methods to a
fusion of multiple score maps at different scales and partition modes, and
adopt it as a robust likelihood for instance segmentation inference. As both
Bayesian inference and map fusion are performed per pixel, BiSeg is a fully
convolutional end-to-end solution that inherits all the advantages of FCNs. We
demonstrate state-of-the-art instance segmentation accuracy on PASCAL VOC.Comment: BMVC201
