In this paper we have proposed Noise Induced HSI model based noisy and blurred colour image segmentation technique. This approach uses additive noise to suppress the effect of internal noise present in an image for proper detection of objects from such images. In this algorithm we decompose a given image in Hue, Saturation and Intensity (HSI) components and then apply processing on intensity component...
In this paper a dynamic stochastic resonance (DSR)-based watermark extraction technique from audio signal in discrete wavelet transform domain has been presented. The watermark embedding has been done in detail coefficient of DWT transformed audio signal. DSR improves the authenticity of the extraction process by utilizing noise or degradation introduced during different signal processing attacks...
In this paper a dynamic stochastic resonance (DSR)-based watermark extraction technique from audio signal using singular value decomposition (SVD) has been presented. Watermark embedding has been done by weighted addition of the binary watermark in the singular values of the audio signal. DSR has been used in the extraction process to improve the authenticity of the extracted watermark by utilizing...
