Estimation program, estimation device, generation method of detection model, learning method, and learning device

An estimation apparatus comprising:

• a storage unit configured to store
• a learned detection model that receives a new image as input to output coordinates of a region of a primary component contained in the new image, a label of the primary component, a score of the primary component, coordinates of a region of a secondary component contained in the new image, a label of the secondary component, and a score of the secondary component, and
• a constituent component model in which a relationship between coordinates of a region of a primary component contained in a prescribed regular constituent object and coordinates of regions of a plurality of secondary components contained in the prescribed regular constituent object are modeled;
• a constituent component detection unit configured to output the coordinates of the region of the primary component contained in the new image, the label of the primary component, the score of the primary component, the coordinates of the region of the secondary component contained in the new image, the label of the secondary component, and the score of the secondary component based on the new image as constituent component detection results by using the learned detection model;
• a bottom-up estimation unit configured to estimate first primary component candidates, based on the constituent component model and the constituent component detection results and sorting out a secondary component that is not registered with a list of the first primary component candidates;
• a primary component merge unit configured to merge a plurality of the first primary component candidates to generate a second primary component candidate;
• and
• a top-down recognition unit configured to select a secondary component matching the second primary component candidate from among a plurality of secondary components sorted out and register the selected secondary component with the second primary component candidate.
