Among approaches in implementing Digital Rights Management, image fingerprinting technique is considered to be one of the most attractive solutions, especially in detecting illegal use of image works....
A Novel VLSI Architecture of Hybrid Image Compression Model based on Reversible Blockade Transform
VLSI Discrete Cosine Transform JPEG Hartley transform
<
2010/2/2
Image compression can improve the performance of
the digital systems by reducing time and cost in image storage
and transmission without significant reduction of the image quality.
Furthermore, the...
A DISTORTION INPUT PARAMETER IN IMAGE DENOISING ALGORITHMS WITH WAVELETS
Signal Processing denoising filtering
<
2010/1/11
The problem of image denoising based on wavelets is considered. The paper
proposes an image denoising method by imposing a distortion input parameter instead
of threshold. The method has two algorit...
