GROUP-SPECIFIC MODEL GENERATION SYSTEM, SERVER, AND NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM FOR RECORDING GROUP-SPECIFIC MODEL GENERATION PROGRAM

A group-specific model generation system includes: a captured image collection circuitry configured to collect a captured image from each of cameras; an image feature extraction circuitry configured to extract a feature from each of the captured images; an image clustering circuitry configured to group the captured image based on the feature of each of the captured images; a camera classification circuitry configured to classify cameras into groups, based on a result of the grouping of the captured images; and a group-specific model generation circuitry configured to generate a group-specific learned neural network model suitable for captured images taken by the cameras in the each of the groups.
