IST - Subjective Evaluation of Viewport Rendering Projections

A crowdsourcing subjective evaluation of viewport images obtained with several sphere-to-plane projections was conducted. The viewport images were rendered from eight omnidirectional images in equirectangular format. The pairwise comparison (PC) method was chosen for the subjective evaluation of projections. More details about the viewport images and subjective evaluation procedure can be found in [1].[1] F. Jabar, J. Ascenso, and M.P. Queluz, “Globally and Locally Optimized Pannini Projection for Viewport Rendering of 360 Images”, Submitted to J. Vis. Commun. Image Represent., Oct. 2022.

一项关于使用多种球面到平面投影获取的视窗图像的众包主观评估实验得以实施。这些视窗图像由八个等角圆柱体格式的全向图像渲染而成。为进行投影的主观评估，选用了成对比较法（PC）。关于视窗图像及主观评估流程的更多详细信息，请参阅[1]。[1] F. Jabar, J. Ascenso, 和 M.P. Queluz, “全局与局部优化帕尼尼投影用于360度图像的视窗渲染”，已提交至《视通讯与图像表示》期刊，2022年10月。
