Combining images with text - G06V: IMAGE OR VIDEO RECOGNITION OR UNDERSTANDING - G06T: IMAGE DATA PROCESSING OR GENERATION, IN GENERAL ## Abstract Some implementations may provide a method for generating a portrait of a subject for an identification document, the method including: receiving, at a mobile device, a photo image of the subject, the photo image including a foreground and a background, wherein the foreground includes the subject's face and the background does not include the subject's face; determining the background of the photo image based on the photo image alone and without user intervention; masking the determined background from the photo image; and subsequently generating the portrait of the subject based on the photo image with the background masked. ## Claims ### Claim 1 A method for generating a portrait of a subject for an identification document, the method comprising: receiving, at a mobile device, a photo image of the subject, the photo image including a foreground and a background, wherein the foreground includes the subject's face and the background does not include the subject's face; determining the background of the photo image based on the photo image alone and without user intervention; masking the determined background from the photo image; and subsequently generating the portrait of the subject based on the photo image with the background masked. ### Claim 2 (depends on 1) The method of claim 1, further comprising: determining the background without calibrating the photo image against an additional photo image that includes either the subject or the background. ### Claim 3 (depends on 2) The method of claim 2, further comprising: masking the determined background without storing data encoding the determined background. ### Claim 4 (depends on 1) The method of claim 1, wherein generating the portrait of the subject further comprises: resizing portions of the foreground that correspond to the subject's face. ### Claim 5 (depends on 1) The method of claim 1, wherein generating the portrait of the subject further comprises: synthesizing a virtual backdrop by replacing the masked background with a synthetic background, the synthetic background comprising a pattern pre-determined for the identification document. ### Claim 6 (depends on 4) The method of claim 4, further comprising: integrating the generated portrait with the synthesized virtual background on the identification document to identify the subject. ### Claim 7 (depends on 1) The method of claim 1, wherein generating the portrait of the subject further comprises: adjusting a region of interest of the subject's hair volume in the foreground. ### Claim 8 (depends on 1) The method of claim 1, further comprising: providing a user interface to allow a user to adjust a region of interest of the subject's hair volume in the foreground. ### Claim 9 (depends on 1) The method of claim 1, further comprising: providing a user interface to allow a user to choose a pixel in the photo image with the background masked and adjust pixel color and value for the chosen pixel. ### Claim 10 (depends on 1) The method of claim 1, wherein generating the portrait further comprises: tracing a boundary that separates the foreground from the background. ### Claim 11 (depends on 10) The method of claim 10, wherein generating the portrait of the subject further comprises: providing a user interface to allow a user to trace a boundary that separates the foreground from the background. ### Claim 12 A mobile device, comprising at least one processor configured to: receive a photo image of a subject taken for generating an identification document of the subject, the photo image including a foreground and a background, wherein the foreground includes the subject's face and the background does not include the subject's face; determine the background of the photo image based on the photo image alone and without user intervention; mask the determined background from the photo image; and subsequently generate the portrait of the subject based on the photo image with the background masked. ### Claim 13 (depends on 12) The mobile device of claim 12, wherein the at least one processor is further configured to determine the background without calibrating the photo image against an additional photo image that includes either the subject or the background. ### Claim 14 (depends on 13) The mobile device of claim 13, wherein the at least one processor is further configured to determine the background by transmitting the photo image of the subject to a server for making the determination. ### Claim 15 (depends on 12) The mobile device of claim 12, wherein the at least one processor is further configured to generate the portrait of the subject by resizing portions of the foreground that correspond to the subject's face. ### Claim 16 (depends on 12) The mobile device of claim 12, wherein the at least one processor is further configured to generate the portrait of the subject by replacing the masked background with a synthetic background, the synthetic background comprising a pattern pre-determined for the identification document. ### Claim 17 (depends on 16) The mobile device of claim 16, wherein the at least one processor is further configured to integrate the generated portrait on the identification document to identify the subject. ### Claim 18 (depends on 16) The mobile device of claim 16, wherein the at least one processor is further configured to replace the masked background without storing information encoding the determined background. ### Claim 19 (depends on 10) The mobile device of claim 10, further comprising: a photo device to adapted capture the photo image of the subject. ### Claim 20 (depends on 12) The mobile device of claim 12, wherein the at least one processor is further configured to: adjust a region of interest of the subject's hair volume in the foreground. ### Claim 21 (depends on 12) The mobile device of claim 12, wherein the at least one processor is further configured to: provide a user interface to allow a user to adjust a region of interest of the subject's hair volume in the foreground. ### Claim 22 (depends on 12) The mobile device of claim 12, wherein the at least one processor is further configured to: provide a user interface to allow a user to choose a pixel in the photo image with the background masked and adjust pixel color and value for the chosen pixel. ### Claim 23 (depends on 12) The mobile device of claim 12, wherein the at least one processor is further configured to: trace a boundary that separates the foreground from the background. ### Claim 24 (depends on 12) The mobile device of claim 12, wherein the at least one processor is further configured to: providing a user interface to allow a user to trace a boundary that separates the foreground from the background. ### Claim 25 A computer-readable medium comprising software instructions that when executed by one or more processors, cause the one or more processors to perform the operations of: receiving a photo image of a subject taken for generating an identification document of the subject, the photo image including a foreground and a background, wherein the foreground includes the subject's face and the background does not include the subject's face; determining the background of the photo image based on the photo image alone and without user intervention; masking the determined background from the photo image; and subsequently generating the portrait of the subject based on the photo image with the background masked. ### Claim 26 (depends on 25) The computer-readable medium of claim 25, wherein the operations comprise determining the background without calibrating the photo image against an additional photo image that includes either the subject or the background. ### Claim 27 (depends on 25) The computer-readable medium of claim 25, wherein generating the portrait of the subject comprises replacing the masked background with a synthetic background, the synthetic background comprising a pattern pre-determined for the identification document. ### Claim 28 (depends on 27) The computer-readable medium of claim 27, wherein the operations further comprise printing the generated portrait on the identification document to identify the subject. ### Claim 29 (depends on 27) The computer-readable medium of claim 27, wherein the operations further comprise replacing the masked background without storing data encoding the determined background.
