Quality Assessment of a Stereo Pair Formed from Two Synthesized Views Using Objective Metrics
نویسندگان
چکیده
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 video plus depth format. The performance of different state-of-the-art 2D quality metrics is analyzed in terms of correlation with subjective perception of video quality. A set of subjective data collected through formal subjective evaluation tests is used as benchmark. Results show that some objective metrics, including PSNR, do not predict well perceived quality of synthesized views. On the other hand, metrics such as VIF, VQM, MS-SSIM, or SSIM have a high correlation with perceived quality.

Improving the quality of images synthesized by discrete cosines transform – regression based method using principle component analysis
Purpose: Different views of an individuals’ image may be required for proper face recognition. Recently, discrete cosines transform (DCT) based method has been used to synthesize virtual views of an image using only one frontal image. In this work the performance of two different algorithms was examined to produce virtual views of one frontal image. Materials and Methods: Two new meth...
متن کاملNew Stereo Video Quality Assessment Metric for Three Dimensional Video Systems
Since traditional two dimensional video quality metrics are not suitable for evaluating stereo video, a new stereo video quality metric based on support vector regression (SVR) for three dimensional video systems is proposed in this paper. Firstly, three factors affecting the quality of stereo video are analyzed, namely left-view video quality, right-view video quality and difference between tw...
متن کاملPerceived quality of DIBR-based synthesized views
This paper considers the reliability of usual assessment methods when evaluating virtual synthesized views in the multiview video context. Virtual views are generated from Depth Image Based Rendering (DIBR) algorithms. Because DIBR algorithms involve geometric transformations, new types of artifacts come up. The question regards the ability of commonly used methods to deal with such artifacts. ...
متن کاملBlind Stereo Image Quality Assessment Inspired by Brain Sensory-Motor Fusion
The use of 3D and stereo imaging is rapidly increasing. Compression, transmission, and processing could degrade the quality of stereo images. Quality assessment of such images is different than their 2D counterparts. Metrics that represent 3D perception by human visual system (HVS) are expected to assess stereoscopic quality more accurately. In this paper, inspired by brain sensory/motor fusion...
متن کاملVisual quality assessment of synthesized views in the context of 3D-TV
DIBR is fundamental to 3DTV applications because the generation of new viewpoints is recurrent. As any tool, DIBR methods are subject to evaluations thanks to the assessment of the visual quality of the resulting generated views. This assessment task is peculiar because DIBR can be used for different 3DTV applications: either in a 2D context (free viewpoint video), or in a 3D context (3D displa...
