Interferometric Ranging System with Hopped Frequencies (IRHF) is a novel ranging technique with advanced anti-jamming capability in wireless sensor networks. This paper investigates the ranging performance of Maximum Likelihood (ML) estimator of IRHF under multi-tone jamming (MTJ), which is a potential threat faced by wireless sensor nodes. Firstly, the jamming model with one malicious node tra...

Segmentation is typically the first step in computer-aided-detection (CADe). The second step is false positive reduction which usually involves computing a large number of features with thresholds set by training over excessive data set. The number of false positives can, in principle, be reduced by extensive noise removal and other forms of image enhancement prior to segmentation. However, thi...
