Segmented high-resolution transmission electron microscopy images of nanoparticles

A collection of high-resolution transmission electron microscopy (HRTEM)
images of crystalline nanoparticles on amorphous substrates and their
corresponding segmentation maps, including 407 raw camera images and
segmentation maps; as well as 13 curated datasets created from this larger
repository. Images cover a variety of microscope magnifications
(0.02-0.042 nm/pixel), electron dosages (80-884 e/Å2), nanoparticle
diameters (2.2-20 nm), nanoparticle material (Au, Ag, CdSe), and substrate
background (ultrathin C, SiN), and have been acquired over multiple
microscope sessions. Segmentation maps were created by a single human
labeler. Digital images are provided to aid in viewing data. 
Datasets have each been curated by metadata characteristics, including
acquisition date, microscope magnification, electron dosage, nanoparticle
material, and nanoparticle diameter. The datasets have been processed from
raw image data and converted into a format conducive for machine learning
training, including flat field correction, pixel value standardization,
and image patching.
