Image database TID2013: Peculiarities, results and perspectives
TLDR
This paper describes a recently created image database, TID2013, intended for evaluation of full-reference visual quality assessment metrics, and methodology for determining drawbacks of existing visual quality metrics is described. Expand
Color image database TID2013: Peculiarities and preliminary results
TLDR
A new database of color images with various sets of distortions called TID2013 is presented that contains a larger number of images and seven new types and one more level of distortions are included. Expand
Synchronization Techniques for Orthogonal Frequency Division Multiple Access (OFDMA): A Tutorial Review
TLDR
The goal of this paper is to provide a comprehensive survey of the latest results in the field of synchronization for OFDMA systems, with tutorial objectives foremost. Expand
Texture analysis and classification with tree-structured wavelet transform
TLDR
A progressive texture classification algorithm which is not only computationally attractive but also has excellent performance is developed and is compared with that of several other methods. Expand
Environmental Sound Recognition With Time–Frequency Audio Features
TLDR
An empirical feature analysis for audio environment characterization is performed and a matching pursuit algorithm is proposed to use to obtain effective time-frequency features to yield higher recognition accuracy for environmental sounds. Expand
Perceptual visual quality metrics: A survey
TLDR
A systematic, comprehensive and up-to-date review of perceptual visual quality metrics (PVQMs) to predict picture quality according to human perception. Expand
Maximum-likelihood synchronization and channel estimation for OFDMA uplink transmissions
TLDR
Simulations indicate that the accuracy of the CFO estimates asymptotically achieves the Cramer-Rao bound and the proposed algorithm requires increased overhead but has more flexibility as it can be used with any subcarrier assignment scheme. Expand
Audio content analysis for online audiovisual data segmentation and classification
TLDR
A heuristic rule-based procedure is proposed to segment and classify audio signals and built upon morphological and statistical analysis of the time-varying functions of these audio features. Expand
A new initialization technique for generalized Lloyd iteration
TLDR
An efficient method is proposed to obtain a good initial codebook that can accelerate the convergence of the generalized Lloyd algorithm and achieve a better local minimum as well. Expand
Design of integrated multimedia compression and encryption systems
TLDR
This research examines the limitations of selective encryption using cryptanalysis, and proposes another approach that turns entropy coders into encryption ciphers using multiple statistical models that can be applied to most modern compressed audio/video such as MPEG audio, MPEG video, and JPEG/JPEG2000 images.
