Image processing device, image processing method, and image processing program for deciding a similarity between a captured image and a sample image

An image processing method comprising:

• detecting, from among a plurality of sample images and a plurality of captured images each of which has a rank, first combinations of the sample images and the captured images of which a similarity is equal to or more than a first threshold value;
• detecting, from among the first combinations, second combinations of the sample images and the captured images in which a difference between the rank of a sample image among the plurality of sample images and the rank of a captured image among the plurality of captured images is within a second threshold value;
• deciding, based on the second combinations, a combination of a sample image group including the sample images and a captured image group including captured images regarded as a same scene as the sample image group;
• deciding, from the captured image group, the captured image of which the similarity with one sample image included in the sample image group is equal to or more than a third threshold value;
• and
• displaying the captured image of which the similarity with the one sample image included in the sample image group is equal to or more than the third threshold value.

A non-transitory recording medium that stores a computer-readable program that controls a computer of an image processing device to:

• detect, from among a plurality of sample images and a plurality of captured images each of which has a rank, first combinations of the sample images and the captured images of which a similarity is equal to or more than a first threshold value more;
• detect, from among the first combinations, second combinations of the sample images and the captured images in which a difference between the rank of a sample image among the plurality of sample images and the rank of a captured image among the plurality of captured images is within a second threshold value;
• decide, based on the second combinations, a combination of a sample image group including the sample images and a captured image group including captured images regarded as a same scene as the sample image group;
• decide, from the captured image group, the captured image of which the similarity with one sample image included in the sample image group is a third threshold value;
• and
• display the captured image of which the similarity with the one sample image included in the sample image group is equal to or more than the third threshold value.
