Watermarking digital images for copyright protection
(IEE, 1996)A watermark is an invisible mark placed on an image that is designed to identify both the source of an image as well as its intended recipient. The authors present an overview of watermarking techniques and demonstrate a ... -
Watermarking digital images for copyright protection
(IEE, 1995)A watermark is all invisible mark placed on an image that can only be detected when the image is compared with the original. This mark is designed to identify both the source of a document as well as its intended recipient. ... -
A wavelet-based Bayesian framework for 3D object segmentation in microscopy
(2012)In confocal microscopy, target objects are labeled with fluorescent markers in the living specimen, and usually appear with irregular brightness in the observed images. Also, due to the existence of out-of-focus objects ... -
Whispering gallery mode emission from photonic microtubes
(IEEE, 2006)We have found cylindrical glass microtubes can be formed by vacuum assisted filtration using a micro-channel glass matrix followed by thermal treatment of the material. The microtubes are strongly luminescent and exhibit ... -
Whispering-gallery modes in photonic tubes
(Society of Photo-optical Instrumentation Engineers (SPIE), 2007)A new method has been developed to fabricate microtube resonators with strong whispering-gallery-mode emission and quality factors up to 3000. -
Whitespace Networks Relying on Dynamic Control Channels
(2013)The emergence of whitespace networks, and whitespace communications in general, provides an opportunity to, at least partially, meet the ever-growing demand for mobile data communication. Most of the whitespace network ... -
Whole-Body Magnetic Resonance Imaging Enables Assessing Spatial Accuracy and Precision of Skeletal Joint Locations Inferred from Motion Capture Systems
(2015)Motion capture systems can be used to infer skeletal joints from three-dimensional surface information for various human poses. However, to-date it remains unclear how well the estimated joint coordinates coincide with ... -

X-ray diffraction study of ferroelectric and antiferroelectric liquid crystal mixtures exhibiting de Vries SmA∗-SmC∗ transitions
(2010)In this Rapid Communication, results on smectic layer thickness, using synchrotron radiation x-ray diffraction, for different mixtures of ferroelectric and antiferroelectric liquid crystals are given. We find that with ...
