In this paper, a new structure for image encryption using recursive cellular automatais presented. The image encryption contains three recursive cellular automata in three steps, individually. At the first step, the image is blocked and the pixels are substituted. In the next step, pixels are scrambledby the second cellular automata and at the last step, the blocks are attachedtogether and the ...

NonGaussian Markov image models are e ective in the preservation of edge detail in Bayesian formulations of restoration and reconstruction problems. Included in these models are coe cients quantifying the statistical links among pixels in local cliques, which are typically assumed to have an inverse dependence on distance among the corresponding neighboring pixels. Estimation of these coe cient...

In three-dimensional television (3DTV), an interactive free viewpoint selection application has received more attention so far. This paper presents a novel method that synthesizes a free-viewpoint based on multiple textures and depth maps in multi-view camera configuration. This method solves the cracks and holes problem due to sampling rate by performing an inverse warping to retrieve texture ...

In this paper a support vector machine based handwritten numerals recognition system of Manipuri Script (Meetei Mayek) is investigated. We have used various feature extraction technique such as background directional distribution (BDD), zone based diagonal, projection histograms and Histogram Oriented Gradient features. In Background Directional Distribution (BDD) features background distributi...

In this paper, we propose an implicit line-based linear intra 16×16 prediction method for high-quality video coding. Typically, in H.264/AVC intra 16×16 vertical and horizontal prediction modes, 256 pixels in the current macroblock are predicted using 16 adjacent boundary pixels of reconstructed neighboring macroblocks. One problem of such a block-based intra prediction is that the prediction e...

A large body of previous models to predict where people look in natural scenes focused on pixel-level image attributes. To bridge the semantic gap between the predictive power of computational saliency models and human behavior, we propose a new saliency architecture that incorporates information at three layers: pixel-level image attributes, object-level attributes, and semantic-level attribut...

Capacitive sensor array (CSA) plays an important role in life science applications, such as cell monitoring, DNA detection, or drug screening. This paper presents a 480×960 time-sharing TDC (ts-TDC) architecture of global shutter CSA. It provides opportunity to merge interfacing, read-out and sampling circuits pixel dynamically adjust the electrode size according characteristic biosample. Each ...
