(a) high-precision automated defect cluster detection and size analysis based on the mapping of defect contrasts to 2D Gaussians(b) analysis of spatial correlations of radiation defects based on 2D pairwise radial distribution function. ρ represents the separation distance of radiation defects. Conditions adopted for experiment data collection: 50-400 keV W+ irradiation, 30 K, fluence about 1016 W+/m2 (no cascade overlap), weak-beam dark-field contrast imaging with g= 200 and 110, excitation error sg=0.12-0.17 nm-1
