Photonic Devices for Imaging, Display, and Storage
Electronic and electro-optic devices are frequently used to display images obtained from the computer processing of data. Images, or digital pictures, are generally two-dimensional data structures that convey spatial information to the viewer. Images are collected through various means, from digital cameras to laser radar scanning systems and, once stored in a computer, can be manipulated mathe...
متن کاملPhotorefractive Materials for Optical Storage and Display
Real -time data storage and processing using optical techniques have been considered in recent years. Of particular interest are photosensitive electro-optic crystals which permit volume storage in the form of phase holograms, by means of a charge transfer process. A survey of the state of the art of such holographic memories is presented. The physical mechanism responsible for the formation of...
متن کاملHalftone Visual Cryptography & Watermarking
R.Charanya, T. Vijayan Abstract: In this Paper, a method of Information hiding & Piracy protection in Image processing is discussed. Visual cryptography & Digital watermarking helps in enables Information hiding, copyright & piracy protection. Here, a technique involving halftone visual cryptography along with watermarking is proposed to achieve visual cryptography via half toning. Digital wate...
متن کاملDigital display of endotracheal tube cuff pressures made simple.
To the Editor:-There are many situations in which monitoring endotracheal tube cuff pressure is desirable. A number of devices have been developed to allow such monitoring. However, one may obtain a continuous digital display of endotracheal tube cuff pressure in the operating room (OR) or intensive care unit using readily available equipment. An ordinary (usually disposable) air-filled pressur...
متن کاملGamut expanded halftone prints
We propose a framework for printing high chroma and bright colors which are beyond both the display sRGB and the classical cmyk print gamuts. These colors are printed with a combination of classical cmyk inks and the two additional daylight fluorescent magenta and yellow inks. The goal is to enhance image parts by printing them with high chroma and bright colors. We first select the image parts...
