چکیده
This paper proposes new and original adaptive image ringing detection and ringing suppression methods. Ringing detection is performed using a scale-space based computational analysis of ideal low-pass filtering of step edges. Edge width conception is introduced and is used to approximate ringing parameter. Method to choose strong isolated edges which are the best suitable edges for ringing analysis is proposed. A method of ringing level estimation for 2D images with unknown ringing parameters is introduced and used to perform real image deringing. New image quality metrics sensible to ringing artifact are introduced and used to analyze image resampling methods.

Perceptually adaptive joint deringing-deblocking filtering for scalable video transmission over wireless networks
Video transmission over low bit-rate channels, such as wireless networks, requires dedicated filtering during decoding for crucial enhancement of the final perceptual video quality. For that reason deringing and deblocking modules are inevitable components of decoders in wireless video transmission systems. Aimed at improving the visual quality of decoded video, in this paper a new perceptually...
متن کاملAdaptive Bilateral Filter for JPEG 2000 Deringing
Ringing artifacts arise near edges in highly compressed JPEG2000 images. This paper is devoted to the study of the optimal bilateral filter parameter selection in image deringing. We propose modification of the bilateral filter: adaptive bilateral filter, where parameters of bilateral filter are changing according to the corresponding pixel. On the first stage calculation of the filter paramete...
متن کاملEfficient implementation of video post-processing algorithms on the BOPS parallel architecture
Deblocking and deringing are two video post-processing techniques largely used to remove coding artifacts and improve the visual quality when rendering low bit rate coded video. The algorithms used to achieve these tasks are computationally intensive and usually require high speed processors to be able to run in real time. Efficient implementations of signal adaptive filters for video post-proc...
متن کاملCompressing medical images by morphology filter voting strategy and ringing effect elimination
We describe a novel medical image coder that adopts a hybrid wavelet deringing algorithm. The proposed algorithm uses spectrum reorganization, classification, block similarity, and a deringing filter to encode medical images. The coefficients of each wavelet tree are organized into a wavelet block to reduce image complexity. Following the spatial location of the block-gathering operation, class...
متن کاملEfficient quadtree based block-shift filtering for deblocking and deringing
The existing implementations of block shift based filtering algorithms for deblocking are hard to achieve good smoothing performance and low computation complexity simultaneously due to their fixed block size and small shifting range. In this paper, we propose to integrate quadtree (QT) decomposition with the block-shift filtering for deblocking. By incorporating the QT decomposition, we can ea...
