image processing applications. In case of image compression, quality of decompressed image is also the criterion for evaluation of given coding scheme. In the process of compression –decompression various artifacts such as blocking artifacts, blur artifact, ringing or edge artifact are observed. However quantification of these artifacts is a difficult task. We propose here novel method to quant...

This report discusses the energy balance results observed during the simulation of the impact of an aluminum sphere on an aluminum plate supported by a hollow aluminum cylinder. Due to the high impact velocity, there is considerable ringing of the cylinder which causes the sum of the mechanical energies to increase. An optimal set of input parameters is identified that minimizes ringing and red...

JPEG2000 Standard is a new generation image compression technique, enabling encoding images at low bitrates with acceptable quality. Since JPEG2000 is based on wavelet transforms, the reconstructed image will contain perceivable ringing artifacts in medium and low bit-rate regimes of lossy compression. This work utilizes a quad-tree partitioning scheme for post-processing the reconstructed imag...

We propose the concept of an optimal inductance value that can substantially reduce delay of global RLC signals while maintaining good signal integrity (low ringing/overshoot). We exploit the fact that inductance results in faster transition times to improve delay of buffers in global signal lines. We observe that voltage overshoot, slew rate, and total line delay all show strong inflection poi...

Currently, the growing of digital video delivery leads to compress at high ratio, the video sequences. Different coding algorithms like MPEG-4 introduce different artifacts (blocking, blurring, ringing) degrading the perceptual video quality. Such impairments are generally exploited by the No-Reference quality assessment. In this paper, we propose to use the principal distortions introduced by ...
