Abstract
An information processing device inspects a target image that contains an image of an inspection target. The information processing device includes a pre-processor, a first calculator, a second calculator, and a determiner. The pre-processor is configured to perform pre-processing for comparing the target image with a reference image or a plurality of reference images. The first calculator is configured to define, in the target image, a region of interest (ROI) and surrounding regions that are adjacent to the ROI, and calculate a feature value of the ROI. The second calculator is configured to calculate an outlier from comparison with feature values of images corresponding to the ROI and the surrounding regions in the reference images. The outlier numerically indicates singularity of an image at the ROI. The determiner is configured to provide, based on the outlier, an indicator to be used for the inspection.
