Since the reforming and opening up of China, domestic and foreign scholars have made deep researches on the total factor productivity of China, but the different estimation results led to much controversy. Herein, the new method is used to estimate the two key indexes of capital and labor input in the paper. Based on that, by extended Solow residual value Method to undertake an empirical study on...
We propose a voting-based pose estimation algorithm applicable to 3D sensors, which are fast replacing their 2D counterparts in many robotics, computer vision, and gaming applications. It was recently shown that a pair of oriented 3D points, which are points on the object surface with normals, in a voting framework enables fast and robust pose estimation. Although oriented surface points are discriminative...
In this paper, we propose an aerial surveillance system utilizing a static camera and a PTZ camera. The static camera captures a wide angle view of the scene, while the PTZ camera is capable of zooming in to a region of interest (ROI) selected by the user and capturing a detailed image. The system consists of a novel tracking algorithm named Simultaneous Estimation, Filtering and Rejection (SEFAR)...
Processing underwater acoustic signals for monitoring and classification are difficult problems that have recently attracted attention in the field of underwater signal processing. For these purposes, it is necessary to use a method which could be able to extract the useful information about the processed data. In this paper, an algorithm of extracting feature from radiated noise of underwater targets...
Wireless Sensor Networks have been proposed for a multitude of location-dependent application. Solutions in range-free localization are being pursued as a cost-effective alternative to more expensive range-based approaches. In this paper, we present an improved midnormal-based localization algorithm. Compared with its former scheme MBLA, our scheme performs with less compute overhead and improve the...
We propose a novel solution to object detection, localization and pose estimation with applications in robot vision. The proposed method is especially applicable when the objects of interest may not be richly textured and are immersed in heavy clutter. We show that a multi-flash camera (MFC) provides accurate separation of depth edges and texture edges in such scenes. Then, we reformulate the problem,...
The difficulty for accurate determination of the angles of arrival (AOA) of signals arises from the optimization of likelihood functions of high dimension. Usually, a gradient-based technique is employed to find the optimum of the function. However, this method requires heavy computational work and the differentiability of the likelihood function. This paper presents two gradient-free methods: One...
