actuate an output device to deliver a first output upon detecting an absence of a seatbelt in the first region and in the second region; and actuate the output device to deliver a second output upon detecting an absence of the seatbelt in the first region and a presence of the seatbelt in the second region. ### Claim 2 (depends on 1) The system of claim 1, the computer further programmed to: actuate the output device to deliver the first output upon detecting an occupant in the image, an absence of the seatbelt in the first region, and an absence of the seatbelt in the second region; and actuate the output device to deliver the second output upon detecting the occupant in the image, an absence of the seatbelt in the first region, and a presence of the seatbelt in the second region. ### Claim 3 (depends on 1) The system of claim 1, the computer further programmed to select a location in the image for the first region at a chest of an occupant. ### Claim 4 (depends on 1) The system of claim 1, the computer further programmed to select a location in the image for the second region above a shoulder and beside a head or neck of an occupant. ### Claim 5 (depends on 1) The system of claim 1, the computer further programmed to actuate the output device to deliver a third output upon determining that an occupant is inattentive. ### Claim 6 (depends on 1) The system of claim 1, wherein the first region is located in the image where a chest of an occupant of 50th-percentile stature sitting in a seat is expected to be located. ### Claim 7 (depends on 1) The system of claim 1, wherein the second region is located in the image above where a shoulder and beside where a head or neck of an occupant of 50th-percentile stature sitting in the seat is expected to be located. ### Claim 8 (depends on 1) The system of claim 1, wherein the first output includes a first actuation of a user interface and a limitation of vehicle speed, and the second output includes a second actuation of the user interface and a limitation of vehicle speed. ### Claim 9 A method comprising: identifying first and second regions of a seatbelt image; actuating an output device to deliver a first output upon detecting an absence of a seatbelt in the first region and in the second region; and actuating the output device to deliver a second output upon detecting an absence of the seatbelt in the first region and a presence of the seatbelt in the second region. ### Claim 10 (depends on 9) The method of claim 9, further comprising: actuating the output device to deliver the first output upon detecting an occupant in the image, an absence of the seatbelt in the first region, and an absence of the seatbelt in the second region; and actuating the output device to deliver the second output upon detecting the occupant in the image, an absence of the seatbelt in the first region, and a presence of the seatbelt in the second region. ### Claim 11 (depends on 9) The method of claim 9, further comprising selecting a location in the image for the first region at a chest of an occupant. ### Claim 12 (depends on 9) The method of claim 9, further comprising selecting a location in the image for the second region above a shoulder and beside a head or neck of an occupant. ### Claim 13 (depends on 9) The method of claim 9, further comprising actuating the output device to deliver a third output upon determining that an occupant is inattentive. ### Claim 14 (depends on 9) The method of claim 9, wherein the first region is located in the image where a chest of an occupant of 50th-percentile stature sitting in a seat is expected to be located. ### Claim 15 (depends on 9) The method of claim 9, wherein the second region is located in the image above where a shoulder and beside where a head or neck of an occupant of 50th-percentile stature sitting in the seat is expected to be located. ### Claim 16 (depends on 9) The method of claim 9, wherein the first output includes a first actuation of a user interface and a limitation of vehicle speed, and the second output includes a second actuation of the user interface and a limitation of vehicle speed. ### Claim 17 A vehicle comprising: a seat; a camera aimed at the seat; and a computer in communication with the camera and programmed to identify first and second regions of a seatbelt image from the camera; actuate an output device to deliver a first output upon detecting an absence of a seatbelt in the first region and in the second region; and actuate the output device to deliver a second output upon detecting an absence of the seatbelt in the first region and a presence of the seatbelt in the second region. ### Claim 18 (depends on 17) The vehicle of claim 17, wherein the computer is further programmed to select a location in the image for the first region at a chest of an occupant and to select a location in the image for the second region above a shoulder and beside a head or neck of the occupant. ### Claim 19 (depends on 17) The vehicle of claim 17, wherein the first region is located in the image where a chest of an occupant of 50th-percentile stature sitting in the seat is expected to be located, and the second region is located in the image above where a shoulder and beside where a head or neck of an occupant of 50th-percentile stature sitting in the seat is expected to be located. ### Claim 20 (depends on 17) The vehicle of claim 17, wherein the first output includes a first actuation of a user interface and a limitation of vehicle speed, and the second output includes a second actuation of the user interface and a limitation of vehicle speed.
