Abstract
Provided is an information-processing device including: a CPU; and a memory storing instructions for causing the information-processing device, when executed by the CPU, to: select M (M≤N) images from N (N>1) images; generate a combined image by arranging the selected M images in M frames defined in advance, respectively; and determine a total assessment value in association with the generated combined image, the total assessment value including at least a linear sum of a selection assessment value being a linear sum of single image assessment values of the selected M images and a combination assessment value being a single image assessment value of the combined image.
Claims11
1:
- An information-processing device, comprising:
- a CPU;
- and
- a memory storing instructions for causing the information-processing device, when executed by the CPU, to:
- select M (M≤N) images from N (N>1) images;
- generate a combined image by arranging the selected M images in M frames defined in advance, respectively;
- and
- determine a total assessment value in association with the generated combined image, the total assessment value including at least a linear sum of a selection assessment value being a linear sum of single image assessment values of the selected M images and a combination assessment value being a single image assessment value of the combined image.

2:
- The information-processing device according to claim 1, wherein the instructions further cause the information-processing device to:
- normalize the selection assessment value based on M being the number of selected images, to thereby determine the total assessment value of each of a plurality of the combined images different in M.
3:
- The information-processing device according to claim 1, wherein the instructions further cause the information-processing device to:
- determine the selection assessment value based on the single image assessment value of each of the selected M images and a weight coefficient corresponding to each of the M frames defined in advance.
4:
- The information-processing device according to claim 1, wherein the total assessment value further includes a linear sum of similarity assessment values each indicating similarity between the selected images.
5:
- The information-processing device according to claim 4, wherein the instructions further cause the information-processing device to:
- normalize the similarity assessment values based on M being the number of selected images, to thereby determine the total assessment value of each of a plurality of the combined images different in M.

7:
- The information-processing device according to claim 1, wherein the combined image includes a fixed image arranged in advance in a portion other than the M frames.
8:
- The information-processing device according to claim 1, wherein the instructions further cause the information-processing device to:
- input the selected image or the combined image into a machine learning model, to thereby acquire the single image assessment value corresponding to the input selected image or the combined image.
9:
- The information-processing device according to claim 1, wherein the instructions further cause the information-processing device to:
