Short-range wireless positioning and inertial measurement unit (IMU) have been widely used in indoor positioning systems. However, wireless signals fluctuate seriously and the accuracy of low-cost IMU system suffers from gyroscope drift, magnetic interference and accumulative error. In this paper, we propose a fusion positioning system based on Wireless signal, Map information and Inertial sensors,...
Wireless Capsule Endoscopy (WCE) is a novel imaging technique for the investigation of the entire small bowel. It produces over 50,000 images per examination. It is a highly time-consuming and labor tedious task to review such a large amount of images. Recent research has focused on developing computer aided diagnosis (CAD) systems to reduce the heavy burden of physicians. In this paper, we propose...
Analysis of Wireless Capsule Endoscopy (CE) images has become a very active area of research since this novel technology enabled access to previously inaccessible areas of the gastrointestinal tract, especially the small intestine. Art has investigated automatic segmentation of organ boundaries, detection of lesions and bleeding as well as other supervised and unsupervised analysis. However, all of...
Mobile video surveillance system based on ARM9 uses unique high-bandwidth business applications of 3G wireless network. The design of hardware and software of embedded monitoring system is described. The running platform of 3G network show that the system can work well in the circumstances of the limited bandwidth.
Wireless Capsule Endoscopy (WCE) is a revolutionary technology that allows physicians to examine the patients whole gastrointestinal tract, especially the small intestine. However, reviewing capsule endoscopic video is a labor intensive task and very time consuming. In this paper we propose a novel method to detect key frames with abnormalities. It is based on the adaptive non-parametric corner detection...
This article researches the channel estimation algorithm based on multi-input multi-output & orthogonal frequency division multiplexing (MIMO-OFDM) system. It is mainly working on the research of channel estimation algorithm based on training sequence least square (LS) criterion. On the basis of introducing the LS time domain channel estimation algorithm, it brings about an improved LS time domain...
Study on the application about a new type BLAST-Random Layered Space-Time (RLST) which presents in this article used in the TD-SCDMA system. After the comparison on the result of theory and the simulation, it compares the performance of the random layered space-time with the general V-BLAST in the CDMA structure, and at the same time it compares the performance of the receiver which is using the RLST...
