I am referring an IEEE's paper for my project which has a term called knee atlas, I am not getting the exact meaning of this term, does they mean it a processed image or something else? I am working in
matlab and here is the paragraph of IEEE's paper:
Six atlases were derived from 3-D DESS WE series from six subjectswith visually normal knee images ... The series for three of these atlases were selected from the public release OAI image dataset 0.D.1 and three were from the baseline pilot study. Trained human observers created the knee MRI atlases using manual segmentation.
