Feature extraction} - G06T 11/60: Creating or editing images; Combining images with text - G06V 10/50: by performing operations within image blocks; by using histograms, e.g. histogram of oriented gradients [HoG]; by summing image-intensity values; Projection analysis - G06V 40/197: {Matching; Classification} - G06V: IMAGE OR VIDEO RECOGNITION OR UNDERSTANDING - G06T: IMAGE DATA PROCESSING OR GENERATION, IN GENERAL ## Abstract Provided is an information processing system including: a comparison information acquisition unit that acquires comparison information regarding iris comparison generated based on an iris image including an iris of a recognition subject; and a display image generation unit that generates a display image including an image indicating a content of the comparison information in association with positions in the iris. ## Claims ### Claim 1 An information processing apparatus comprising: a memory configured to store instructions; and a processor configured to execute the instructions to: acquire feature amount information of irises extracted from a first iris image and a second iris image; generate a first display image based on the first iris image and a second display image based on the second iris image; and output the first display image and the second display image, wherein each of the first display image and the second display image includes a ring-shaped image indicating at least one of a matching region, a non-matching region, and a non-comparable region in an iris comparison, and a rectangular image indicating at least one of the matching region, the non-matching region, and the non-comparable region in the iris comparison, wherein the at least one of the matching region, the non-matching region, and the non-comparable region is distinguished and displayed on the first display image and the second display image. ### Claim 2 (depends on 1) The information processing apparatus according to claim 1, wherein each of the ring-shaped image and the rectangular image indicates the at least one of the matching region, the non-matching region, and the non-comparable region with a predetermined color. ### Claim 3 (depends on 1) The information processing apparatus according to claim 1, wherein the processor is further configured to execute the instructions to: display the ring-shaped image, which includes the image indicating the at least one of the matching region, the non-matching region, and the non-comparable region, superimposed on the first iris image. ### Claim 4 (depends on 1) The information processing apparatus according to claim 1, wherein the feature amount information includes a plurality of blocks associated with the positions in the iris, and wherein a code extracted from the first iris image and the second iris image is set for each of the plurality of blocks. ### Claim 5 (depends on 4) The information processing apparatus according to claim 4, wherein the code has one value selected from at least three types of values. ### Claim 6 (depends on 4) The information processing apparatus according to claim 4, wherein the code is extracted based on a brightness of the first iris image. ### Claim 7 (depends on 4) The information processing apparatus according to claim 4, wherein the at least one of the matching region, the non-matching region, and the non-comparable region in the iris comparison is determined based on the code. ### Claim 8 An information processing method comprising: acquiring, by a processor, feature amount information of irises extracted from a first iris image and a second iris image; generating, by the processor, a first display image based on the first iris image and a second display image based on the second iris image; and outputting, by the processor, the first display image and the second display image, wherein each of the first display image and the second display image includes a ring-shaped image indicating at least one of a matching region, a non-matching region, and a non-comparable region in an iris comparison, and a rectangular image indicating at least one of the matching region, the non-matching region, and the non-comparable region in the iris comparison, wherein the at least one of the matching region, the non-matching region, and the non-comparable region is distinguished and displayed on the first display image and the second display image. ### Claim 9 A non-transitory computer-readable medium having stored therein a program executable by a processor for performing a method comprising: acquiring feature amount information of irises extracted from a first iris image and a second iris image; generating a first display image based on the first iris image and a second display image based on the second iris image; and outputting the first display image and the second display image, wherein each of the first display image and the second display image includes a ring-shaped image indicating at least one of a matching region, a non-matching region, and a non-comparable region in an iris comparison, and a rectangular image indicating at least one of the matching region, the non-matching region, and the non-comparable region in the iris comparison, wherein the at least one of the matching region, the non-matching region, and the non-comparable region is distinguished and displayed on the first display image and the second display image.
