WebThe algorithms combine both the robustness of the Speeded-Up Robust Features technique (SURF) and Discrete Wavelet Transform (DWT) to achieve characteristic region Steganography synchronization. The book also touches on how to avoid hiding data in the whole image by dynamically selecting characteristic regions for the process of embedding.
WebJul 7, 2015 · For example, the simplest algorithm would be to follow the jpeg encoding process (split image in 8x8, DCT each block, quantise coefficients) and then apply your steganography algorithm on those integer coefficients as if they are pixels. Then carry on with the jpeg encoding by saving those coefficients in a jpeg format. – Reti43 five nights at freddy\u0027s crayonsWebSteganography is the science of hiding secret information in any cover medium like image or video, for the purpose of secure transmission.
