In this paper we propose a novel super-resolution algorithm based on motion compensation and edge-directed spatial interpolation succeeded by fusion via pixel classification. Two high-resolution images are constructed, the first by means of motion compensation and the second by means of edge-directed interpolation. The AdaBoost classifier is then used to(More)
For practical applications there is a requirement of the global motion estimation that could use existing block matching motion data. In this paper authors propose two global motion estimation methods that are based on block matching motion estimation. These methods estimate different global motion models. One of the proposed method advantages consists in(More)
Algorithms for video content compression have been developed very fast during last years. But most of them are still lossy. This fact leads to different artifacts appearing in compressed video due to information losses. Objective metric for blocking artifacts detection and a number of methods for blurring estimation are proposed in this article. They can(More)
Creating and processing stereoscopic video imposes additional quality requirements related to view synchronization. In this work we propose a set of algorithms for detecting typical stereoscopic-video problems, which appear owing to imprecise setup of capture equipment or incorrect postprocessing. We developed a methodology for analyzing the quality of S3D(More)
Automatic analysis of stereo-video quality plays an important role in the process of capturing, converting and editing video in 3D format. Although several low-level stereo-video quality metrics were proposed, a lot more challenging problems of high-level stereo-video analysis, such as left-right channel swap detection, are still practically unsearched. The(More)
This research aims to sufficiently increase the quality of visual-attention modeling to enable practical applications. We found that automatic models are significantly worse at predicting attention than even single-observer eye tracking. We propose a semiautomatic approach that requires eye tracking of only one observer and is based on time consistency of(More)
