Adaptive Watermarking Algorithm of Image Based on the Human Visual System
2012 Edition, October 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Considering the robustness and imperceptibility of digital image watermarking, this paper proposes an watermark embedding algorithm, in which watermark is embedded in DC coefficients derived from a dual DCT transformations. After block based DCT transformation, DC coefficients of an...

A motion adaptive deinterlacing method based on human visual system
2011 Edition, Volume 1, October 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Based on the analysis of conventional deinterlacing methods, a new motion adaptive deinterlacing method is proposed. In this paper, we improve three aspects of the conventional motion adaptive method. Firstly, we add a FIR filter to the motion detection...

A fast noise reduction method based on human visual system
2003 Edition, Volume 3, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

To perform well, an image noise reduction method should be built upon an effective noise detection scheme. However, almost all the noise reduction methods published in recent years are in lack of a well-designed noise detection scheme. As a matter of fact, they are nothing more than only...

Zerotree wavelet image coding based on the human visual system model
1998 Edition, January 1, 1998 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we consider an application of perceptual optimization to the zerotree wavelet image coding. Three main properties of the Human Visual System (HVS) are incorporated into the coder: frequency sensitivity, luminance sensitivity and texture...

Human visual system based similarity metrics
2008 Edition, October 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Objective assessment of image quality is important for a number of image processing applications. Similarity metrics have been used for methods such as automating compression, automating watermarking, and benchmarking algorithm success. The goal of objective quality assessment is to quantify...

Human visual system models in Digital Watermarking
2015 Edition, October 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, a review of Human Visual System (HVS) based Digital Watermarking schemes are presented with their mathematical model. The HVS system exploits several properties of human eyes in spatial as well as frequency domain. In spatial domain,...

A drawing scene perception model based on the human visual system
1992 Edition, January 1, 1992 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Conventional drawing recognition systems can process only objects that are segregated from each other and distinctly regularized in terms of geometric properties such as location, size, and orientation. On the other hand, humans can recognize objects easily even in a...

Assessment of noise reduction based on human visual system
2012 Edition, September 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The performance of the noise reduction algorithm is evaluated by the quality metric using relation between pre-NR and post-NR images. The quality metric in the JND unit reflects the reduction of the block noise visibility and the preservation...

Human visual system based VOP extraction
1999 Edition, January 1, 1999 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

One of the main problems associated with object based video coding systems, is how to efficiency extract objects. MPEG-4 is an object based system using video object planes (VOPs), however MPEG-4 does not define how VOPs are extracted from video sequences. This...

Adaptive watermarking technique based on human visual system and fuzzy inference system
2013 Edition, May 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A robust image watermarking scheme based on human visual system is proposed. The perceptual quality of the watermarked image is controlled by determining adaptive scaling factor for each individual pixel value. To determine the adaptive...
