Magnetic tracking systems have been increasing in popularity due to their lower expense and small size of their tracked objects, but they are sensitive to ferromagnetic objects within their work volumes. Optical tracking systems can overcome this disadvantage, however there are some occlusions problem in optical system. Hence, we present a novel hybrid localization system combining optical one and...
The Wireless Capsule Endoscopy (WCE) has been gradually used in hospitals due to its breakthrough that it can view the whole gastrointestinal with less suffering. Nevertheless, it generates too many images each time causing a huge burden to physicians; therefore it's meaningful to help physicians to employ computerized methods to diagnose. One important way is to build up three-dimensional (3D) model...
In order to assess the compliance of Ingested Wireless Device (IWD) within safety guidelines, the Specific Absorption Rate (SAR) and near fields of IWD in two realistic human body models whose dielectric values are changed from the original by ±±10 and ±±20% are studied using the Finite-Difference Time-Domain (FDTD) method. The radiation characteristics of the IWD in the human body models with changed...
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...
