hvs

HVS is a global consulting and services organization focused on the hotel, restaurant, shared services, gaming, and leisure industries.

Moreover, we consider the characters of HVS (Human Visual System), consequently watermark has nice invisibility.

The wavelet coefficients are selected by Human Visual System (HVS) to ensure the transparence of watermarking.

Using HVS to choose the adaptive strength of embedding, it has a better invisibility and robustness.

The comparisons show that the HVS-based indirect-embedding schemes have a promising application in the copyright control of paper products.

This thesis mainly studies adaptive digital image watermarking algorithms based on human visual system (HVS).

Firstly, a watermark was embedded in low band of DWT domain according to the conceal quality of human visual system (HVS).

An image noise detection model was given and two no-reference quality assessment methods based on HVS were proposed.

We presented a novel watermarking method based on wavelet packets transform and human visual system(HVS).

A nature scene image color-texture feature extraction method based on human visual system(HVS) was proposed.

In this paper, a novel fragile watermarking scheme based on HVS in DWT domain is proposed.

According to the HVS's characteristic, the watermarking embedding intensity is determined at the same time.

We detected a significant quantity of endotoxin in the artery and in the portal and the HVs (P 0. 001).

Objective: To study the relationship between hyperviscosity syndrome (HVS) and platelet membrane glycoproteins (GP) sub-group changes.
