As each copy undergoes a distinctive warp, collusion through averaging either yields low-quality results or requires substantial computational resources to undo random warps. ...
Multiple users may, however, collude and collectively escape identification by creating an average of their individually watermarked copies that appears unwatermarked. ...
For instance, if the host signal is an image the average appears to have multiple ghost images or is a blurred version. In either case, the colluded copy is a rather low quality version. ...

To efficiently analyze an image, the quality of the image should be high standard and thus, enhancement of image quality has become imperative in image analysis systems. ...
In this paper, two techniques, Laplacian Pyramid-based image fusion and Wavelet-based image fusion algorithms are considered and their applicability to fuse sonar images to construct an enhanced image ...
Thus, the wavelet transform decomposes the image into lowhigh, high-low, high-high spatial frequency bands at different scales and the low-low band at the coarsest scale. ...

First, research on the responsiveness of high and low self-monitors to image-oriented and product-quality-based advertising attempts is addressed. ...
Findings suggest that when judging product quality, low self-monitors tend to rely on product performance and high self-monitors more likely use the product's image-enhancing capabilities. ...
For this multiple-function product, high self-monitors generated more image-oriented/social-identity and less quality-based/utilitarian copy than did low self-monitors. ...
