PedCut: an iterative framework for pedestrian segmentation combining shape models and multiple data cues

This paper presents an iterative, EM-like framework for accurate pedestrian segmentation, combining generative shape models and multiple data cues. In the E-step, shape priors are introduced in the unary terms of a Conditional Random Field (CRF) formulation, joining other data terms derived from color, texture and disparity cues. In the M-step, the resulting segmentation is used to adapt an Active Shape Model (ASM), after which the EM process alternates.
