1. A non-transitory computer-readable medium storing a computer program executed by a computer processor to execute a process comprising:
acquiring a medical image generated based on a signal detected by a catheter inserted into a luminal organ;
detecting an object region included in the medical image by inputting the acquired medical image into a model trained for detecting the object region included in the medical image;
detecting the object region in units of pixels by semantic segmentation in the model;
acquiring an output of an activation function included in the model in each pixel included in a predetermined region of the medical image using the model;
calculating reliability of each of a plurality of boundary points located on a boundary between the detected object region and another image area in the medical image;
calculating the calculated reliability of a boundary point included in the predetermined region based on a ratio of pixels in which the output of the activation function to all the pixels included in the predetermined region of the medical image is within a predetermined range;
correcting the boundary based on a detection result of the object region by the model by performing interpolation using the boundary points at which the calculated reliability satisfies a predetermined standard; and
generating screen information that displays the detected object region.
