Subjective Evaluation of Higher Dynamic Range Video

High dynamic range (HDR) imaging is able to capture a wide range of luminance values, closer to what the human eye can perceive. However, for capture and display technologies, it is important to answer the question on the significance of higher dynamic ran ...

Objective quality metrics for video scalability

Touradj Ebrahimi, Francesca De Simone, Adrien Georges Jean Besson

Scalable video coding is emerging as an efficient alternative to simulcast encoding to distribute the same video content si- multaneously to many users having different terminals and network conditions. In order to select the best combination of video scal ...

Paired comparison-based subjective quality assessment of stereoscopic images

Touradj Ebrahimi, Jong Seok Lee, Lutz Goldmann

As 3D image and video content has gained significant popularity, subjective 3D quality assessment has become an important issue for the creation, processing, and distribution of high quality 3D content. Reliable subjective quality assessment of 3D content ...

Benchmarking of quality metrics on ultra-high definition video sequences

Touradj Ebrahimi, Philippe Hanhart

The performance of objective quality metrics for high-definition (HD) video sequences is well studied, but little is known about their performance for ultra-high definition (UHD) video sequences. This paper analyzes the performance of several common object ...

Quality Assessment of a Stereo Pair Formed From Two Synthesized Views Using Objective Metrics

Touradj Ebrahimi, Philippe Hanhart

When a stereo pair is formed from two synthesized views, it is unclear whether objective 2D quality metrics can provide a good estimation of the perceived quality. In this paper, this problem is addressed considering a 3D video represented in multiview vid ...

Sample and Pixel Weighting Strategies for Robust Incremental Visual Tracking

Michel Bierlaire, Jean-Philippe Thiran, Javier Cruz Mota

In this paper, we introduce the incremental temporally weighted principal component analysis (ITWPCA) algorithm, based on singular value decomposition update, and the incremental temporally weighted visual tracking with spatial penalty (ITWVTSP) algorithm ...

Predicting 3D Quality based on Content Analysis

Touradj Ebrahimi, Philippe Hanhart

Development of objective quality metrics that can reliably predict perceived quality of 3D video sequences is challenging. Various 3D objective metrics have been proposed, but PSNR is still widely used. Several studies have shown that PSNR is strongly cont ...

Estimation of cylinder quality measures from quality maps for Minutia-Cylinder Code based latent fingerprint matching

Andrzej Drygajlo, Mohammad Hamed Izadi

Poor quality of fingerprint data is one of the major problems concerning latent fingerprint matching in forensic applications. Local quality of fingerprint plays a very important role in this application field to ensure high recognition performance. Al- th ...

User-Action-Driven View and Rate Scalable Multiview Video Coding

Vladan Velisavljevic

We derive an optimization framework for joint view and rate scalable coding of multi-view video content represented in the texture plus depth format. The optimization enables the sender to select the subset of coded views and their encoding rates such that ...

On the evaluation of 3D codecs on multiview autostereoscopic display

Touradj Ebrahimi, Philippe Hanhart

Evaluating the performance of different 3D codecs on multiview autostereoscopic monitor is a tedious process, as it requires the synthesis of a dense set of views. Therefore, it is legitimate to ask if evaluations could be performed on stereoscopic monitor ...
