Weighted image generation apparatus, method, and program, determiner learning apparatus, method, and program, region extraction apparatus, method, and program, and determiner

A weighted image generation method comprising:

• displaying a medical image from which at least one region of interest is extracted on a display;
• correcting a boundary of the region of interest according to a correction instruction for the extracted region of interest;
• and
• generating a weighted image in which each pixel in the medical image has, as a pixel value of each pixel, a weight coefficient representing a certainty of being within the region of interest, by setting an initial weight coefficient for the extracted region of interest and setting a corrected weight coefficient for a corrected region based on the correction instruction in the medical image.

A non-transitory computer-readable storage medium that stores a weighted image generation program causing a computer to execute:

• displaying a medical image from which at least one region of interest is extracted on a display;
• correcting a boundary of the region of interest according to a correction instruction for the extracted region of interest;
• and
• generating a weighted image in which each pixel in the medical image has, as a pixel value of each pixel, a weight coefficient representing a certainty of being within the region of interest, by setting an initial weight coefficient for the extracted region of interest and setting a corrected weight coefficient for a corrected region based on the correction instruction in the medical image.
