In this paper we present a model-based image steganography method in discrete wavelet
transform (DWT). This method is based on the human visual system model. The proposed …

Background removal of an identity (ID) picture consists in separating the foreground (face,
body, hair and clothes) from the background of the image. It is a necessary groundwork for …

Visual masking plays a crucial role in optimizing distortion position and intensity in
information hiding. However, existing studies on stereoscopic visual masking effects are …

In stereo image hiding, the stereo visual masking model can guide us choose confidential
information's location and intensity while kee** the subjective quality unchanged. The …

2-D Just-Noticeable-Distortion (JND) models based on monocular vision properties are
used to measure the just imperceptiule distortion threshold of an image. When a pair of …

Faber Schauder discrete wavelet transform (FSDWT) has many interesting advantages in
image and video processing owing to its simplicity and its multiscale-based theory. It …

Perceptual image watermarking consists in using knowledge of the Human Visual System
(HVS) to choose the strength of the watermark according to image properties. This paper …
