Opis:: The paper presents the methodology for 3D video subjective quality evaluation. Described methodology was designed to compare different 3D video compression technologies without an influence of any particular displaying or rendering technology. In addition detailed step by step description of test session design and preparation is provided. Experimental results for state-of-the-art 3D encoders are also included. All tests were conducted on two 3D monitors (polarization and autostereoscopic) thus influence of different displaying technologies on 3D video quality assessments has also been evaluated.

Opis:: In literature, oriented filters are used for low-level vision tasks. In this paper, we propose use of steerable Gaussian filter in image quality assessment. Human visual system is more sensitive to multidirectional edges present in natural images. The most degradation in image quality is caused due to its edges. In this work, an edge based metric termed as steerable Gaussian filtering (SGF) quality index is proposed as objective measure for image quality assessment. The performance of the proposed technique is evaluated over multiple databases. The experimental result shows that proposed method is more reliable and outperform the conventional image quality assessment method.

Tytuł:: Is a Multi-Slider Interface Layout Responsible for a Stimulus Spacing Bias in the MUSHRA Test?

MUSHRA
Opis:: The multi-stimulus test with hidden reference and anchors (MUSHRA) is commonly used for subjective quality assessment of audio systems. Despite its wide acceptance in scientific and industrial sectors, the method is not free from bias. One possible source of bias in the MUSHRA method may be attributed to a graphical design of its user interface. This paper examines the hypothesis that replacement of the standard multi-slider layout with a single-slider version could reduce a stimulus spacing bias observed in the MUSHRA test. Contrary to the expectation, the aforementioned modification did not reduce the bias. This outcome formally supports the validity of using multiple sliders in the MUSHRA graphical interface.
