A Novel VLSI Architecture has been developed for Color Mosaic Images. The architecture was designed for implementation on an FPGA. The proposed work presents the integration of Color Image Mosaicing and Encoder Architecture in order to mosaic image/video sequences in real time. Novel algorithms for the image mosaicing have been designed using ASM charts. The image mosaicing architecture is coded using...
The appearance of the face will vary drastically when pose, illumination, background and expression change. Variations in these conditions make Face Recognition (FR) an even more challenging and difficult task. In this paper, we propose two novel techniques, viz., Entropic Gabor Wavelet Transform (Entropic-GWT) and Logarithmic Binary Particle Swarm Optimization (LBPSO), to improve the performance...
Face Recognition (FR) under varying pose, background and illumination conditions is challenging. In this paper, we propose four novel techniques, viz., Dual Pose testing (DPT), Color Based Background Removal (CBBR), Wavelet filtering and Modified Binary Particle Swarm Optimization (MBPSO), to improve the performance of a FR system. DPT is used to neutralize pose variations, CBBR removes cluttered...
The appearance of the face varies drastically when background, pose and illumination change. Variations in these conditions make Face Recognition (FR) an even more challenging and difficult task. In this paper, we propose two novel preprocessing techniques, viz., Entropy Augmented Face Isolation (EAFI) and Image Folding, to improve the performance of the FR system. EAFI is used to localize the face...
In this paper, a new technique for the enhancement of color image using multiscale retinex with modified color restoration has been proposed. The basic steps of multiscale retinex algorithm have been analyzed, modified and various operations are performed in an orderly manner. The enhancement effects are visually effective. In addition, it adds true color constancy to an image. The experimental results...
This paper investigates the improvements to the quality of ocean color data using an appropriate choice of ancillary data for National Oceanic and Atmospheric Administration (NOAA) operational ocean color data processing, which requires routine ocean color product production in near real time. The ancillary data, such as the total column ozone amount, sea surface wind speed, atmospheric pressure,...
