Claim 6:
7. A surgery assistance method comprising:
calculating, from a human-body internal image captured using an endoscope, a feature amount of a target part image corresponding to a target part, the feature amount including feature extraction information, region information, confidence information, and heatmap information, wherein the feature extraction information indicates features of the target part image extracted from the human-body internal image, the region information indicates a position and a size of a window region with which a part or an entirety of an image corresponding to the target part is detected from the feature extraction information, the confidence information indicates the probability of the image in the window region being an image corresponding to the target part, and the heatmap information is calculated using the feature extraction information;
calculating a similarity degree of the confidence information between different human-body internal images, including the human-body image; and
calculating, based on determining that the similarity degree of the confidence information is greater than or equal to a predetermined confidence value, at least one of a similarity degree of the feature extraction information between the different human-body internal images, a similarity degree of the region information between the different human-body internal images, and a similarity degree of the heatmap information between the different human-body internal images; and
identifying the target part image in each of the different human-body internal images if the similarity degree is greater than or equal to a predetermined value.
