Local Binary Pattern (LBP) and its variants are effective and popular descriptors for texture classification. Most LBP like descriptors have disadvantages including sensitiveness to noise and inability to capture long distance texture information. In this paper we propose a simple, efficient, yet robust multi-resolution descriptor to texture classification — Binary Rotation Invariant and Noise Tolerant...
With the development of China economy and auto industry, urban road noise increased rapidly, which seriously interferes with the normal lives and work orders of residential areas, schools, hospitals, job agencies and others on both sides of urban roads. At present, the urban road traffic noise pollution control in the urban environment has become a hot spot problem. And with the continuous expansion...
The railway passenger car speed enhancement and car body lightweight development could cause insufficient stiffness and poor sound insulation of the railway passenger car body. Thus, the passengers ride comfort decreases. The vibration tests of the high speed railway passenger car are completed using the HEAD acoustics multi-channel vibration test and analysis system. The vibration characteristics...
The image registration based on the features of the image is a major research direction.The points feature is used in traditional registration methods,but the lines and other basic features are ignored. So,an image auto registration method based on natural heterogeneous features is given out. First, the feature points are detected using Harris feature detector and the feature line segments are detected...
In this paper, historical background and fundamental concept of chopper stabilized amplifiers are introduced. Then effects of noise and residual offset are analyzed. Several techniques to reduce the residual offset are proposed. Also some of the disadvantages of chopper stabilization technique, as compared to correlated double sampling technique, are stated. Applications of chopper stabilized amplifiers,...
Continuous-time Delta-Sigma modulators are able to operate at higher frequencies than their discrete-time counterparts. However, they suffer more severely from non-idealities such as clock jitter. A method for measuring this clock jitter has been proposed. Moreover, the effect of the non-ideality are explained and a continuous-time to discrete-time conversion method is presented in order to aid in...
Image registration based on the features of an image is a major research direction. It is common sense that there are many problems in traditional feature registration including a large amount of computations, high complexity and low accuracy. So, an auto image registration method based on natural characteristic points and global homography is proposed in this paper. In this method, firstly, the feature...
