A new method is proposed to address the problem of template drift, a common phenomenon in which the target gradually shifts away from the template in object tracking. This paper integrates drift monitoring and drift correction with template matching. During the tracking based on template matching, drift is corrected once it is detected. The robustness and practicality of the method have been proven...
In this paper we propose a gait recognition method with dynamic gait energy image (DGEI) and manifold learning. First we present a new gait feature-dynamic gait energy image which can reflect the dynamic variance parts of the motion body and can better characterize gait features. Secondly in order to preserve the principal and discriminant components, we use PCA and LPP to discover the low-dimensional...
Deception is an everyday occurrence across all communication media. Deception detection on Chinese text is vital to the safety of people's life, the survival of enterprises and the stability of the country. Inundated with massive amounts of textual information transmitted through computer-mediated communication (CMC), people remain largely unsuccessful and inefficient in detecting those messages that...
In this paper, a descreening algorithm based on wavelet is given. Wavelet decomposition is used to eliminate the halftone noise while preserving most of the original image contents. First, convert the color image to color space CMYK with the linear transformation. Then design the corresponding filter according to the direction of each channel after wavelet decomposition. Furthermore, optional nonlinear...
Multi-sensor information fusion (MSIF) technology, is being widely applied to the modern military field. For the sake of implementing effectively detection and rapid exact identification for the chemical agent in sea-battlefield, and applying MSIF technology in Naval Ships Chemical Detection (NSCD) field, the NSCD system based on the multi-sensor fusion model is built. At the same time, connecting...
