This paper presents a sum of squares (SOS, for brevity) approach to polynomial fuzzy observer design for polynomial fuzzy systems. First, we briefly summarize previous results with respect to a polynomial fuzzy system and controller that are more general representation of the well-known Takagi-Sugeno (T-S) fuzzy system and controller, respectively. Secondly, we propose a polynomial fuzzy observer...
In this research, we propose a method to extract scallop areas in seabed images in order to construct a system that can measure automatically the number, size, and state of fishery resources, especially scallops, by analyzing seabed images. Our algorithm is based on information on the hue and characteristic pattern scallop shells. The effectiveness of the proposed method is illustrated through an...
This paper presents a development of a 4WD omnidirectional wheelchair with a chair tilting system for climbing single high step. For enhancing the step climb capability of standard wheelchairs, a Four-wheel-drive(4WD) mechanism is introduced. The mobile platform equips four wheels. A pair of front-rear wheels which mounted on the same side of the mechanism, are interconnected by belt transmissions...
We extract the mood of disquiet on street corners in real-time with stereo video camera systems. Last year we proposed a novel stereo measurement algorithm to detect moving people, which was focusing on moving region in video data. In this paper, we report our prototype of probabilistic inference engine that can detect contexts of individual pedestrian and groups of pedestrians. We demonstrated that...
A novel method for extraction of moving objects in an image sequence using multi-tiered pulse-coupled neural network (PCNN) is presented in this paper. PCNN is a biologically inspired model, which shows highly applicable in various image processing applications, including image segmentation, contour detection, etc. In order to adapt PCNN for moving object extraction, the multi-tiered PCNN model is...
