Blocking artifact detection and reduction in compressed data
A novel frequency-domain technique for image blocking artifact detection and reduction is presented in this paper. The algorithm first detects the regions of the image which presen...

Reduction of Blocking Artifacts in Block-Based Compressed Images
Abstract. A novel frequency domain technique for image blocking artifact reduction is presented in this paper. For each block, its DC and AC coefficients are recalculated for artif...

Reduction of Blocking Artifacts in Block Transformed Compressed Color Images
In this paper we use the information in the chrominance bands to reconstruct color block transformed compressed images. For the luminance and the two chrominance channels, we de n...

Coding Artifact Reduction using Non-Reference Block Grid Visibility Measure
In this work a new method is proposed for coding artifact reduction of MPEG compressed video sequences. The method makes use of a simple cost-effective technique that allows the b...

Detecting Digital Image Forgeries by Measuring Inconsistencies of Blocking Artifact
Digital images can be forged easily with today’s widely available image processing software. In this paper, we describe a passive approach to detect digital forgeries by checkin...
