Target detection against narrow band noise backgrounds
We studied the detectability of narrow band random noise targets embedded in narrow band random noise backgrounds as a function of differences in center frequency, spatial frequency bandwidth and orientation bandwidth between target and the immediately adjacent background. Unlike most target detection experiments the targets were not added to the background; they replaced the underlying backgro...
متن کاملMulti-channel signal detection using time-varying estimation techniques
We propose to improve the performance of a generalized coherence (GC) detector using noise-suppressed estimates obtained from time varying (TV) techniques. In source detection and localization, the presence of a common but unknown signal must be detected using data from several noisy channels. If one of the channel outputs has a sufficiently high SNR, then it could be pre-processed to improve d...

متن کاملSignal Detection in Fixed Pattern Chromatic Noise
This study is part of a project to develop image discrimination models that can predict the detectability of target signals in color images. Image discrimination models take as input two images and predict the number of just-noticeable differences (JNDs) between the images. If one image is a background image and the other image has the identical background plus a target image, the model predict...
متن کاملNoise-tolerant signal detection in genetic circuits
Cells manage information encoded both in amplitude and frequency modulated signals (AM, FM). Biochemical networks processing these signals have to be able to extract infromation from the very noisy intracellular environment. The interactions between the different molecules and their properties (i.e. their sign and strength), determine the signal detection and filtering capabilities of these net...
