The machines can work like human or even better with the rapid development of the artificial intelligence (AI) in nowadays. More and more researchers have taken the demand about the interactivity of machine seriously. Human motion recognition that is a fundamental topic in robotics that try to make the machines to understand humans action. While the existing frameworks of motion recognition often...
In this work, a fast shape searching face alignment (F-SSFA) algorithm based accelerator is proposed to achieve real-time processing. Firstly, a learning based low-dimensional SURF feature is introduced to reduce the computation cost in the cascaded regression. Then the Euclidean distance and shape affine transformation are utilized to accelerate the shape searching procedure. F-SSFA therefore greatly...
A precise time-to-frequency conversion based on nonlinear pulse shaping is demonstrated. Simulation results also show the scheme can be applied to arbitrary waveform.
Iterative method based on Eric's work for serpentine mode converter design is established. It makes use of steepest ascent technique to search the local optimum, and jump mechanism can be learned to find the global optimum if necessary. Step size is given and works well during the procedure. Structure control methods can be used to realize some structural characteristics. Three kinds of mode converters...
In robot soccer competition, it is important that the robot can identify and approach the ball quickly and accurately. This paper presents a fuzzy control method which could improve the accuracy and speed to recognize ball. The conventional robot control consists of methods for path generation and following. When a robot moves away the desired track, it must return immediately, and while doing so,...
To improve the quality of the self-lubricating spherical plain bearing, a new technology of Two-way neck forming process for the manufacture of the self-lubricating spherical plain bearing was brought out. The shape of the bearing out ring blank was optimized by the parametric finite element method to minimize the necking force in the bearing neck forming process. The two-way necking die was designed...
In bearings-only passive location and tracking, observer maneuver is critical to ensure observability and to obtain an accurate emitter location. In this paper, the author presents an observer maneuver control method based on minimizing the GDOP(geometrical dilution of precision) of target location, in order to achieve a best estimation accuracy at each second of location process. The method for optimizing...
