This paper presents a robust and blind watermarking scheme for copyright protection of images in discrete wavelet transform domain based on the support vector machines (SVMs). This scheme is based on the relation between the coefficients in various sub bands in discrete wavelet transform decomposition. The proposed scheme is very secured and robust to(More)
Digital Watermarking and data hiding has become an important tool for protecting digital images from theft, illegal copying and unlawful reproduction. Some digital watermarking algorithms were proposed using spatial domain and transform domain. The transform domain could be DFT, DCT, DWT or SVD. Several digital watermarking algorithms using Genetic(More)
Digital Watermarking and data hiding have gained popularity in recent years as a means of protecting digital images from theft, illegal copying and unlawful reproduction.

Sweet sorghum bagasse represents a potential low-cost biomass which can be valorized to produce different value-added lignocellulosic platform chemicals of economic importance. The focus of the present study is the pretreatment of sweet sorghum bagasse for efficient delignification, separation of pure cellulose and its structural characterization. Sweet(More)
Genetic Algorithm is proposed. The proposed scheme is based on quantization step size optimization using the Genetic Algorithm to improve the quality of watermarked image and robustness of the watermark. Experimental results are compared with the proposed method and the algorithm proposed by Rui et al. in terms of Normalized Cross correlation (NC) and Peak(More)
Computer Vision is gaining importance with wide applications in video surveillance, video retrieval and analysis, and human - computer interaction. Detection and recognition of human action from the video databases is really a difficult and challenging task. In this paper, video based human action detection and recognition is addressed and performed on KTH(More)
The proposed system presents power-control strategies of a grid-connected hybrid generation system with versatile power transfer. This hybrid system allows maximum utilization of freely available renewable energy sources like wind and photovoltaic energies. For this, an adaptive MPPT algorithm along with standard perturbs and observes method will be used(More)
A turn fault in the stator winding of a generator causes a large circulating current to flow in the shorted turns. If left undetected, turn faults can propagate, leading to phase-ground or phase-phase faults. Incipient detection of turn's faults is essential to avoid hazardous operating conditions and reduce down time. At present the synchronous generators(More)
