Finger vein is a unique physiological biometric for identifying individuals based on the physical characteristics and attributes of the vein patterns in the human. The technology is currently in use or development for a wide variety of applications, including credit card authentication, automobile security, employee time and attendance tracking, computer and network authentication, end point se...
Multiple description (MD) coding is a source coding technique for information transmission over unreliable networks. In MD coding, the coder generates several different descriptions of the same signal and the decoder can produce a useful reconstruction of the source with any received subset of these descriptions. In this paper, we study the problem of MD coding of stationary Gaussian sources wi...
The frequency of meningeal dissemination (MD) in primary CNS lymphoma (PCNSL), its prognostic impact, and optimal management have not been defined thus far. In 69 of 92 (75%) immunocompetent patients, primarily diagnosed with PCNSL at our institution between January 1994 and February 2007, cerebrospinal fluid was analyzed for MD. MD was found by cytomorphology in 7/63 (11%), by immunophenotypin...
Image filtering is a essential part of image processing. There are various filter are available but gives better result only for particular noise. Median filter are one of them median filter give better result for 'salt and pepper' noise but when we use this filter in Gaussian noise not give better result. We are proposing a new median filter with some modification of existing median ...
DWM (Directional weighted median) filter is very popular in filtering digital image and remove mixed noise. Fuzzy logic implemented with median filters to improve its performance. In the previous work, fuzzy system switching gives better performance than directional as well filter. Experimenting same didn’t yield results therefore parameters has been changes per strong points of a constant incl...
In many communication and signal-processing systems, desired signals (sequences) are embedded in noise. Linear filters have been the primary tool for smoothing or recovering the desired signal from the degraded signal. Linear filters perform particularly well where the spectrum of the desired signal is significantly different from that of the interference. In many situations, however, the spect...
