Abstract |
In this paper,a new biometric encryption algorithm is presented based on Modified Logistic system in order to meet the requirements of Biometric Encryption(BE).The Biometric Trait is transformed based on M-Logistic System.The Results of several experimental,Statistical analysis and key sensitivity tests show that the proposed biometric encryption scheme provides an efficent security. |

Abstract |
Various tone mapping operators are available for mapping the high dynamic range images to displayable low dynamic range image. In this paper, the performance of various tone mapping operators are evaluated and compared. Multiple exposure photos are combined together to form a high dynamic range image and tone mapping operators are applied to form a LDR image and the tone mapped images are compared with the original image. Tone mapping is also applied directly on a high dynamic range image and the result is compared with the original image. Color correction formula [13] is applied on the tone mapped images to enhance the image quality and the effect of color correction is also evaluated. Piecewise Tone mapping operator [3] is improved by applying Hierarchical tone mapping operation [4] to enhance the quality of the tone mapped image |

Abstract |
The objective of this paper proposes an
algorithm to forecast the stock market trend based on the
inter day financial time series data. The research focus is
confined to the thrust area of combinational quantitative
technical algorithms overcoming the limitations of other
techniques. A systematic study is performed to individually
evaluate best known time series analytics for their
predictability for profitable stock trades. Also, when
multiple non-correlated time series analytics are combined,
there is a possibility to improve the predictive power. The
combined performances of selective financial indicators are
studied and the combinational patterns that maximize
profitable trades as well as result in high return on
investment are explored in this paper. The outcome of this
exploration has yielded a unique algorithms, namely, Time
Series Quantitative Analytics 1 (TSQA1) is presented in this
paper. |
