A Level Set Method for Joint 3-D Motion Estimation and Segmentation in Range Image Sequences
Abderrahman Hmimia, Amar Mitiche · 2011
The purpose of this study is to investigate a variational method for joint 3-D motion segmentation and estimation in a sequence of range images of a scene containing moving rigid objects viewed by a possibly moving camera. The objective functional contains two terms. One term measures the conformity of the interpretation within each region of 3-D motion segmentation to the range images sequence, and the other term is for the regularity of segmentation boundaries. Minimization of the functional result in concurrent 3-D motion segmentation by curve evolution, and 3-D motion by least squares within each region of segmentation. Curve evolution is implemented via level sets for topology independence and numerical stability. Several sequences of range image are provided which verify the method and its implementation. 1
