The modified histogram shifting method proposed by Hong et. al.(2010) is best method of reversible watermarking[16]. The shifting of pixels are more in Hong et. al.(2010) method. Even Hong et. al.(2010) method of modified histogram shifting has less embedding capacity and do not provide enough quality for general purpose image. Our forward modified histogram shifting method overcomes all these ...

In Gradient Echo (GE) images, susceptibility artifact induces both intravoxel dephasing and pixel shifting (Fig. 2-a) leading to intensity and geometric distortions [1] that may disturb image analysis. In previous works, correction of GE images is assessed by modifying acquisition parameters or by using specific sequences [2]. All the proposed techniques always constrain the acquisition process...

Digital watermark is a technique used to protect the ownership of images and their associated software. A useful watermark scheme should be visually imperceptible and must be robust to resist various attacks: such as JPEG compression, pixel-shifting, cropping, blurring, etc. In this paper, we propose a public watermarking system to protect image processing software and images. We embed a binary...

This work presents a novel robust wavelet-tree-based watermarking method based on structure-based quantization. Wavelet-trees are arranged into super-trees. The watermark bits are then embedded into the super-trees by using the proposed structure-based quantization method. Next, the super-trees are quantized into a significant structure according to these bits. The quantized super-tree has a st...

In Japan, members of the workforce undergo a general health examination (GHE) in accordance with the Occupational Safety and Health (OSH) law and related regulations. Because of a marked increase in the number of workers with health risk factors related to lifestyle, the focus of the GHE is gradually shifting to prevention of lifestyle-related diseases. Under the 1996 amendments to the OSH law ...

objectives: the attentional control scale is a self- report questionnaire that assesses individual differences in attentional control. despite its extensive use, the psychometric properties of the persian version of the acs are not well understood. thus, the present study aimed at investigating the psychometric properties of the attentional control scale and its relationship with symptoms of an...
