Perceptual watermarking should always take full advantage of the results from human visual
system (HVS) studies. Based upon visual saliency's modulation effect which incorporates …

Image enhancement is a process, rather a preprocessing step, through which an original
image is made suitable for a specific application. The application may vary from thermal …

Steganography is the technique of hiding confidential information within multi-media. People
often get confused among steganography and cryptography because both of them are …

This paper presents a model for detection of a specific steganographic method that embeds
message in the video domain. At first the video frames are extracted from an. avi file. The …

The recent increase in the demand for process optimisation, something which we continually
learn from nature, help the telecommunication arena to rapidly evolve into a more scalable …

Методы скрытого встраивания данных в легальные сообщения (стеганографические
методы) применяются для решения двух задач: скрытая передача информации и …

Предложен алгоритм выявления стеганографических вставок, реализуемых в виде
подмены наименее значащих битов. Данный алгоритм основан на методе анализа …

Watermarking in images is necessary for authentication of digital library based applications,
mostly. For efficient utilization of storage space and bandwidth of communication channel …

This paper describes a scheme to encode an image using another reference image in such
a way that an end user can retrieve the encoded image only with the reference image. Such …

A multiple color image segmented watermarking scheme based on discrete wavelet
transform (DWT) and singular value decomposition (SVD) is presented. In the proposed …
