چکیده

Ringing artifacts arise near edges in highly compressed JPEG2000 images. This paper proposes original image ringing detection and suppression techniques. On the first stage edge detection and ringing estimation algorithms are applied to calculate the ringing map of a compressed input image. On the second stage this ringing map is utilized to adjust the smart bilateral filter for effectively protecting the image detail from blur effect. Experimental results show that the proposed smart bilateral filter allows to remove ringing artifacts while introducing no additional blurring and thus to increase visual quality of compressed JPEG2000 images.

Adaptive 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...

A PDE-based method for ringing artifact removal on grayscale and color JPEG2000 images

As successor to JPEG, JPEG2000 aims to realize a very low bitrate. Although JPEG2000’s rate distortion has been improved by approximately 30% against JPEG, as on most images compressed using overlapping transforms-based algorithms, one can notice visible spurious oscillations, or ringing artifacts, around the edges of a JPEG2000-compressed image. In this paper, we propose a Partial Differential...

Morphological De-ringing Filter Design for JEPG-2000

JPEG2000 plays an important role in image data compression. However, JPEG-2000 produces noticeable image degradation, so-called “ringing artifacts,” in the vicinities of edges in reconstructed images, especially when the images are highly compressed. Ringing artifacts result in artificial contours, thus so degrading the quality of decoded images. To improve the visual quality of decoded images ...

Morphology De-ringing Filter Design for Ultrasound Images

Various medical image compression techniques have been proposed for accelerating image propagation in many applications. JPEG2000 is a new generation technique that can encode near lossless ultrasound images at medium bit-rate with diagnostically acceptable quality. Because the coder of JPEG2000 is based on wavelet transform, the reconstructed image will contain some ringing artifacts. Some de-...
