LBP can work robustly with respective to light variation on rich texture regions but not so efficiently on uniform regions. In the latter case, color information should overcome LBP{\^{a}}€™s limitation. Due to the illumination invariance of both the LBP feature and the selected color feature, the method is able to handle local illumination changes such as cast shadows from moving objects. Due to the use of a simple layer-based strategy, the approach can model moving background pixels with quasiperiodic flickering as well as background scenes which may vary over time due to the addition and removal of long-time stationary objects. Finally, the use of a cross-bilateral filter allows to implicitly smooth detection results over regions of similar intensity and preserve object boundaries. Numerical and qualitative experimental results on both simulated and real data demonstrate the robustness of the proposed method.}, pdf = {https://publications.idiap.ch/attachments/papers/2007/Yao_CVPR-VS2007_2007.pdf} } crossreferenced publications: @TECHREPORT{Yao_Idiap-RR-67-2007, author = {Yao, Jian and Odobez, Jean-Marc}, projects = {Idiap, CARETAKER}, month = {5}, title = {Multi-Layer Background Subtraction Based on Color and Texture}, type = {Idiap-RR}, number = {Idiap-RR-67-2007}, year = {2007}, institution = {Idiap}, abstract = {In this paper, we propose a robust multi-layer background subtraction technique which takes advantages of local texture features represented by local binary patterns (LBP) and photometric invariant color measurements in RGB color space.
