Computer program, information processing method, and information processing device

An information processing method for causing a computer to execute processes comprising:

• acquiring a medical image generated based on a signal detected by an imaging catheter inserted to a lumen organ;
• estimating a position of an object at least included in the acquired medical image by inputting the medical image into a first learning model configured to estimate the position of the object included in the medical image;
• extracting, from the medical image, an image portion based on the estimated position of the object included in the medical image;
• and
• recognizing the object included in the extracted image portion by inputting the extracted image portion into a second learning model configured to recognize the object included in the image portion.

An information processing device, comprising:

• a processor configured to;
• acquire a medical image generated based on a signal detected by an imaging catheter inserted to a lumen organ;
• input the acquired medical image into a first learning model configured to output information indicating an estimated position of an object at least included in the medical image;
• receive, an image portion extracted from the medical image based on the estimated position of the object included in the medical image;
• and
• input the extracted image portion into a second learning model configured to output information indicating the object included in the image portion.
