Quality assessment is one of them from two different points of view: objectively or subjectively. In this paper, we propose to study the performance of different metrics belonging to various categories including simple mathematical metrics, humand perception based metrics and spherically optimized ...
Second, we survey the related works on both subjective and objective visual quality assessment (VQA) of 360° video/image. Third, we overview the compression approaches for 360° video/image, which either utilize the spherical characteristics or visual attention models. Finally, we summarize this ...
Viewport proposal CNN for 360 video quality assessment. In Proceedings of the 2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), Long Beach, CA, USA, 15–20 June 2019; pp. 10169–10178. [Google Scholar] Publisher’s Note: MDPI stays neutral with regard to ...
(RF) algorithms on the same dataset. The results indicate that the multi-output DNN model outperforms the single-output DNN model, multi-output DT, and multi-output RF across all assessment measures, proving that the multi-output DNN model is more suitable for multi-category e-commerce ...
by some as heavy and/or bulky, which led to facial discomfort. Not all agreed with this assessment, with some reporting the headset as being both comfortable and light. Others reported the headset to be initially uncomfortable, but claimed that this was addressed by adjusting the headset straps...
Assessment of virtual guides’ credibility in virtual museum environments. In Augmented Reality, Virtual Reality, and Computer Graphics: Proceedings of the 6th International Conference, AVR 2019, Santa Maria al Bagno, Italy, 24–27 June 2019, Proceedings, Part II 6; Springer International Publishing:...
A systematic assessment of the spatial accuracy has not yet been performed. However, cross-sections of the overlapping surface meshes indicate that the position of a point on the fruit’s surface has a maximum deviation of about 0.1 mm between the different meshes. Therefore, all data are ...
An assessment of the virtual tour as a tool for learning is also conducted. This paper details the results obtained by comparing both visualization technologies, highlighting the fact that when using virtual reality headset, results obtained in the immersion subscale are similar to those with the ...
2.3.5. Human Assessment Another possible evaluation is the human evaluation, often crowdsourced, as in [38] on online platforms. Users are presented with multiple images and are asked to choose which one they prefer. Because generated samples present artefacts that are not always eliminated by lo...
