VFITex

To test interpolation performance on various texture types, we developed a new test set, VFITex, which contains twenty 100-frame UHD or HD videos at 24, 30 or 50 FPS, collected from the Xiph, Mitch Martinez Free 4K Stock Footage, UVG database and pexels.com. This dataset covers diverse textured scenes, including crowds, flags, foliage, animals, water, leaves, fire and smoke. HD patches were center-cropped from the UHD sequences, preserving the original UHD characteristics. All frames in each sequence were used for evaluation, totaling 940 quintuplets.
