SMALL NODULES LOCALIZATION ON CT IMAGES OF LUNGS
Computed Tomography Lungs Solitary Pulmonary Nodules Segmentation Localization
2017/6/19
According to the World Health Organization (WHO) lung cancer remains the leading cause of death of men among all malignant tumors [1, 2]. One of the reasons of such a statistics is the fact that the l...
Algorithm and Systematic Approach for Robustness of Ultrasound TOA based Localization
Algorithm Systematic Approach Robustness Ultrasound TOA Localization
2016/1/23
Indoor localization using Time-of-Arrival (TOA)of ultrasound is accurate, but remarkable errors may occur occasionally due to effects by indoor environment issues, such as when ultrasound propagates i...
Framing attacks on smart phones and dumb routers: tap-jacking and geo-localization attacks
