The energy function of active contour model is not convex, so the solution of a minimization problem is prone to fall into a local minimum. Dealing with the problem, this paper proposed a novel convex active contour model for interactive color image segmentation. It defined a new energy function including not only image edge and color information, but also a spatial information term which was adaptively fused with the color information. It defined the spatial information term by fuzzy connectedness and introduced to get more accurate segmentation results. In the energy numerical minimization process, it used split Bregman method to obtain a global solution. Experimental results demonstrate that the proposed method can accurately and quickly get desired segmentation results. [ABSTRACT FROM AUTHOR]

This paper introduced the design and implementation of a multi-function vehicle bus controller with completely China-owned intellectual property. It also covered the development of the corresponding monitoring and testing equipment. The core functionality was implemented on both FPGA based firmware and ARM based software. It developed the whole system with a design-for-reliability methodology. In addition to various self-monitoring and auto-recovery design features, the whole system had been statically checked and field tested with state-of-the-art hardware and software verification techniques. Moreover, it also adopted a modular design styles so that the hardware and software modules could be integrated into a whole spectrum of products with varying admiration and communication capabilities. Thanks to the modular design style, it also introduced a realtime MVB traffic monitoring device and an automatic product tester. With world-leading performance, the proposed MVB controller has passed the IEC61375 conformance test and 20 000 km fault-free operation in a metropolitan subway system. [ABSTRACT FROM AUTHOR]
