This paper proposes a novel detection approach for dim targets with low signal-to-noise ratios in an image sequence. Initially, the superposition analysis is introduced to reveal the relationship between target energy and noise energy in the overlapped images, which is vital for the effectiveness of singular value decomposition, and also the relationship of signal-to-noise ratios to angles between...
With the rapid development of modern information technology, target recognition plays an increasingly important role in agricultural production, national defense construction. However, the existing target recognition algorithm has many limitations, such as image distortion, difficult to recognize target image or poor recognition results because of camera angles and lighting conditions. Based on the...
With the popularization of computer and network in recent years, the information degree of daily life is increasing, the demand for information transmission and processing is increasing too. Data flow in the network transmission is very large, it is necessary to propose effective data stream processing method. Compressed sensing can reconstruct the entire signal with cost a small amount of observed...
This paper proposes a method for defect detection and localization based on singular value decomposition and two-side compressive measurements. First, the feasibility of the singular value decomposition for defect detection and localization is analyzed, then the invariance of the geometrical structure of the rows or columns of the raw data and the compressive data is justified, so the energy and pattern...
