In the following approach, RGB images were converted into modified CIElab version i.e. linearized color space Yy,Cx,Cz. Here color channel Yy has been filtered through contrast sensitivity function of luminance channel. Cx and Cz color channel has been filtered through Chrominance contrast sensitivity function (CSF) model. The filtered data had been divided into 4*4 blocks. Binary pattern for each...
Brain computer interfacing (BCI) plays an important role as an assistive device for various neural disorder people. In this paper, attempts have been made to interface thought process generated in photoplethysmography (PPG) with machine/computer. PPGs were collected by using PPG electrodes on fingertips corresponding to two types of brain activities, planning and relax. The proposed scheme is based...
Advances in the field of information technology also make information security an inseparable part of it. In order to deal with security, Authentication plays an important role. This paper presents a review on the biometric authentication techniques and some future possibilities in this field. In biometrics, a human being needs to be identified based on some characteristic physiological parameters...
In this paper, we have provided a heuristic approach for the refinements of corpus based on regular expressions and its possible applications in the field of Opinion Mining. The proposed work is based on a corpus of reviews. The crude corpus is the raw html files containing reviews. This html file is refined further for the ease of our work so that we can get only the required part from that page...
