Removed images with an aspect ratio greater than 3.0. Removed images with min(width, height) < 200. Removed images with a score of OpenNSFW2 or GantMan/NSFW higher than 0.5. Removed all duplicate images based on the image pHash value from external public datasets. ImageNet-1K/21K, Flick...
Nanocrystalline materials in general are structurally featured by a large density of grain boundaries and large surface/volume ratio, which have attracted significant interest for their unique mechanical, chemical and electronic properties. 1-3 Transmission electron diffraction (TED) is an appropriate ...
