It has been reported that chronic heroin intake induces both structural and functional changes in human brain; however, few studies have investigated the carry-over adverse effects on brain after heroin withdrawal. In this paper, we examined the neurophysiological differences between the abstinent heroin addicts (AHAs) and healthy controls (HCs) using nonlinear dynamic analysis and source localization...
The precession feature of space target provides an effective approach for target recognition. However, with the requirements that target detection and tracking to be completed successfully before the processing of precession features extraction can be implemented, the existing methods demand radar resources allocation for target detection, tracking and feature extraction, respectively, thus reducing...
A major problem in image-based research studies on transmission lines monitoring is to find the corresponding points from different images of the same object. In the paper, matching the pictures of transmission lines which are photoed by the camera on the iron tower with different parameters are studied. we use sub-window registration, symmetric features and Harris corner detection to obtain fast...
3D-TV is well expected as next advancement in television. The conversion technique of two-dimensional (2D) images to 3D images is an effective way to alleviate the shortage of 3D contents. The most important and difficult problem in 2D-to-3D conversion is how to generate or estimate depth information using only a single-view image. In this paper, a new approach to estimate depth map from monocular...
The purpose of this study was to improve the segmentation performance of the level set method for magnetic resonance images (MRI), such as fuzzy boundary or low contrast. In this paper, a level set method was presented in which fuzzy c-means (FCM) was used to prevent boundary leaking during the curve propagated. Firstly, FCM algorithm was used to compute the fuzzy membership values for each pixel,...
