1. A computing device comprising:
a memory to store instructions; and
a processor operatively coupled to the memory, wherein execution of the instructions causes the processor to:
receive an image comprising a face of a person;
calculate a sharpness metric for a region of interest in the image that comprises a current dentition of the person, wherein data for pixels inside of the region of interest is used to calculate the sharpness metric, and wherein data for pixels of a second region that is outside of the region of interest is not used to calculate the sharpness metric;
determine whether the sharpness metric satisfies a sharpness criterion; and
perform one or more additional operations responsive to determining that the sharpness metric satisfies the sharpness criterion, wherein the one or more additional operations comprise generating a modified version of the image, wherein the current dentition of the person is replaced with a post-treatment dentition of the person in the modified version of the image.
