This paper presents a method to extract heading information from the sky light polarization pattern and successfully implements the polarized light compass (PL-compass) under foliage environment with heavy occlusions for the first time. A classifier based on the primal support vector machine is trained to detect the sky area, and the random sample consensus algorithm is used to choose the inliers...
The remarkable polarization vision of animals provides a significant inspiration for robotic navigation and visual enhancement, as polarization pattern provides additional information besides spectral signatures. A novel bio-inspired polarization camera is proposed in this paper, which can realize real-time image-based polarization measurement. The composition of the system is described and the optimal...
Workflow is the technology of implementing automated process. It has a wide use in many fields. The study of workflow engine is a key problem of implement of workflow system. The traditional workflow engine has many limits in practice. In order to reduce cost, shorten developing cycle and raise product competitiveness, open source softer ware become more and more popular in enterprise application...
