Ringing and Blur Artifact Removal in Image Processing Applications
M.K. Kaushik, G.C. Chandrakala, R. Abhinay · 2018
In this work we present an effective ringing and blur artifact removal method to produce ringing free deblur images. Quality evaluation of an image is a prime task in image processing applications. Blur occurs during filtering or visual data compression and ringing occurs by the quantization or truncating of the high frequency transform coefficients resulting from DCT or wavelet based coding. And also, the process of compression and decompression has various artifacts such as blocking artifacts, blur artifact, ringing or edge artifact. However quantification of these artifacts is a difficult task. We propose a novel method to quantify blur and ringing artifact in an image.
