When designing wavelet transforms for subband coding systems, a\nproblem of concern is to avoid ringing effects in the compressed images.\nWe developed a technique to minimize this effect which enables for\ncoding gain optimization. We design wavelets without sidelobes, a\ncondition which is ...

We emulate the effect of myopia by convolving sharp text images with the PSFs and display the results on a regular LCD display Viewsonic VA2448 with contrast ratio 1000:1. We then use our algorithm to compute the pre- compensated images such that after being blurred by the myopia PSFs, ...

we propose a method that reduces the effect of a stronger signal region on a weaker signal in a nearby ROI by designing a postprocessing filter that steers the strong interference away from the ROI, The proposed method is computationally simple both in the design stage and in applying it to...

Blocking effect and ringing noise are two well-known artifacts in low bit rate coded video. The blocking effect is the grid noise along block boundaries mainly visible in smooth areas, and the ringing noise shows along object borders. Traditionally, de-blocking filters try to remove the unwanted...
Because of the shortage of prior information in the blind restoration processing, the result of restoration is usually not satisfactory. Ringing effect is one of the important factors that influence restoration image quality. It is difficult to do the postprocessing and the quality assessment of ...
Image restorationRinging suppressionFor many image reconstruction (deconvolution) problems, particularly in the field of astrophysics, the "ringing" effect around bright point sources (or more generally in the vicinity of abrupt variations of the intensity) is a prominent artifact. This effect appears ...
