In this paper, one of new maximum a posteriori (MAP) estimation methods is introduced for signal detection in a magnetic recording channel with burst erasures. In signal detection for the recoded data sequence on the recording media, it needs to consider that there exists a fluctuation range for the variance of media noise according to the specific recorded bit patterns. Most of conventional signal...
Removal of view disturbing noise from an image obtained with a camera under adverse weather conditions is important. In this paper, we present a method of removing glare caused by water droplets, or other foreign objects, adhering to an imaging lens or its protective glass. We have designed and implemented an electronically controlled optical shutter array that detects and removes glare. Our system...
Authors have studied a radar system with two dimensional array antennas to find survivors accidentally buried in rubble from the top under noisy environment. This paper concentrates on the two issues to improve the survivor-detection abilities. One is a method for the measurement of three dimensional location of each antennas by using ARToolkit. The other is a method for the reduction of impulsive...
