Quantitative image matching was used to compare experimentally observed grain boundary structures and predicted model structures for the strontium titanate Σ3(112) grain boundary. Initially, quantitative image matching of image regions containing bulk crystal were used to determine the specimen and microscope parameters, including specimen thickness and tilt, and image defocus. Using the fitted values for thickness and defocus, images were simulated from two proposed model structures of the SrTiO3 Σ3(112) grain boundary and quantitatively matched to experimental images
