Fig. 4: Comparison to UMAP-projections using natural image and symmetry-aware features.
From: Symmetry-aware recursive image similarity exploration for materials microscopy
Nine (9) next-nearest neighbors in UMAP-projected space near a random piezoresponse force microscopy image for the (a) VGG-16, and (b) ResNet-34-Symm-Aware model. The images determined to be semantically similar are marked with a green-star, and those deemed different are marked with a red x. These images were extracted by finding the nearest neighbors in Euclidian space from a selected image in the UMAP projection. The selected image is marked original. The nearest neighbors are sorted by increasing Euclidean distance from the original randomly selected image.
