A Study onFace Detection and Image Steganographyusing Discrete Wavelet Transform
Journal Title: IOSR journal of VLSI and Signal Processing - Year 2018, Vol 8, Issue 2
Abstract
There are many methods available for secret data hiding and transfer, among which steganography stands out in various aspects. Steganography is used for secret data transfer in a cover object which may be an image, video, audio, text or a network protocol, with an additional advantage of even hiding the existence of such a secret data. Selfies are commonly trending via social media nowadays and can be utilized for image steganography in many cases. A study of face detection using Viola-Jones object tracking method and then embedding secret image into it based on Discrete Wavelet Transform(DWT) technique is executed in MATLAB. Finally, using the steganographic characteristics such as the MSE (Mean Square Error) and PSNR (Peak Signal-to-Noise Ratio) values, the different input cover image formats like JPG, PNG, BMP with secret images of JPG, BMP, PNG formats are analyzed.
