Speckle noise caused by interference of electromagnetic waves complicates Synthetic aperture radar (SAR) images to be interpreted and further practical application, therefore reducing speckle noise an...
Overcomplete representations are attracting interest in signal processing theory, particularly due to their potential to generate sparse representations of signals. However, in general, the problem o...
Reduction of speckle noise is one of the most important processes to increase the quality of radar coherent images. Image variances or speckle is a granular noise that inherently exists in and degra...
Fixed pattern noise (FPN) or nonuniformity caused by device and interconnect parameter variations across an image sensor is a major source of image quality degradation especially in CMOS image sensors...
As CMOS technology scales, the effect of 1/f noise on low frequency analog circuits such as CMOS image sensors becomes more pronounced, and therefore must be more accurately estimated. Analysis of 1/f...
Temporal noise sets a fundamental limit on image sensor performance, especially under low illumination and in video applications. In a CCD image sensor, temporal noise is well studied and characterize...
Temporal noise sets the fundamental limit on image sensor performance, especially under low illumination and in video applications. In a CCD image sensor, temporal noise is primarily due to the photod...
In signal detection theory (SDT), responses are governed by perceptual noise and a flexible decision criterion. Recent criticisms of SDT (see, eg, Balakrishnan, 1999) have identified violations of its...
Lightning and other atmospheric noise interferes with Loran signal reception. This paper develops techniques to improve signal availability under these conditions.
With its wide bandwidth and large amplitude spikes,atmospheric noise can dominate the Loran band (90-110kHz). Data collection efforts over the spring and summer of 2005 in Norman, OK and over th...
Thermal and atmospheric noise distort envelope measurements in a Loran receiver, and may cause the receiver to select the wrong cycle during signal acquisition. A cycle error would persist during sign...
With its large-amplitude and short-duration pulses,atmospheric noise, produced by electrical discharges within clouds, dominates the low-frequency spectrum. Unless mitigated, this noise, which enters ...
The performance of III-V heterojunction bipolar transistors (HBTs) has improved significantly over the past two decades. Today’s state of the art Indium Phosphide (InP) HBTs have a maximum frequency o...
Recently, multi-view distributed video coding (MDVC) receives more and more attention, as its lowcomplexity encoder and high-complexity decoder coding paradigm suits for many applications such as sens...
Image authentication has applications in security systems, photo forensics, and photo journalism. This paper presents an image authentication scheme using added signal-dependent noise. Imperceptible n...
