This paper develops a robust vision-based mobile manipulation system for wheeled mobile robots. In particular, the paper addresses the retention of visual features in the field of view of the camera, which is an important robustness issue in visual servoing. First, the classical approach of Image-Based Visual Servoing (IBVS) for fixed-base manipulators is extended to wheeled mobile robots. Second,...
DCT is widely used in watermarking, but the effect of different coefficients on robustness and fidelity remains unclear. For example, there is only one DC coefficient, but many low frequency coefficients, so error correcting coding can be applied to improve the robustness of the low frequency coefficients, and in this situation, how about the robustness between a single DC coefficient and all the...
An experimental study was developed to investigate how users perceived product material texture. The semantic differential (SD) method, cluster analysis and protocol analysis were employed to examine users' material texture cognition of plastic samples. Completed in computer by g.eneral statistics software, the cluster analysis results revealed that the samples can be described with neutral, substantial,...
In the recent years visual servo control has become a popular research topic in robotics. Usually, it is applied to fixed-base robotic manipulators working in a structured industrial environment. This paper focuses on developing a visual servo control system for a mobile robot, which operates in an unstructured environment. First, the system hardware and control objective are introduced. Second, the...
