At present scenario, there is growing demand for the software system to recognize characters in a computer system when information is scanned through paper documents. This paper presents detailed review in the field of Optical Character Recognition. Various techniques are determined that have been proposed to realize the center of character recognition in an optical character recognition system...

While different optical flow methods continue to appear , there has been a lack of quantitative evaluation of existing methods. For a common set of image sequences , we report the results of regularly cited techniques , including instances of differential, matching, energy-based, and phase-based approaches.

In this tutorial paper, we present the application of well-known DSP techniques used in lower speed wireline and wireless applications, to high-speed optical communications. After an introduction on today’s optical network architecture and typical optical channel impairments, we study techniques such as fiber equalization, maximum likelihood detection, and current and next generations Forward E...

The robustness of various modulation formats and equalization techniques to fiber impairments is reviewed, including an MLSD strategy for high-order modulation . The analytical and simulation methods adopted for performance evaluation are also presented.

The overwhelming scatter which occurs when optical radiation propagates through tissue severely limits the ability to image internal structure using measurements of transmitted intensity. A broad range of methods has been proposed during the past decade or so in order to improve imaging performance. Direct methods involve isolating an unscattered or least-scattered component of transmitted scat...

This paper provides an overview of the current research in the field of optical techniques for cervical neoplasia detection and covers a wide range of the existing and emerging technologies. Using colposcopy, a visual inspection of the uterine cervix with a colposcope (a binocular microscope with 3- to 15-fold magnification), has proven to be an efficient approach for the detection of invasive ...

Integrated photonics has emerged as an I/O technology set to disrupt the communication fabric of many-core computer systems. The optical technology uses wavelength-division-multiplexing and a high degree of integration in order to surpass electrical I/O in both throughput and energy by more than an order of magnitude. However, integrated photonic systems need to be properly designed in order to...
