Abstract
A method includes determining, from a first image of a mouth, a first region of the first image comprising a representation of teeth; generating one or more parametric functions associated with tooth color based on color data from the first region; receiving image data comprising new contours of the mouth, wherein one or more of the teeth have a different position in the image data than in the first image; determining a second region comprising the teeth in the image data; and generating a new image based on the image data and the one or more parametric functions, wherein a shape of the teeth is based on the image data and a color of the teeth is based on applying the one or more parametric functions to the second region of the image data.
Claims20
A non-transitory computer readable medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- determining, from a first image of a mouth, a first region of the first image comprising a representation of teeth;
- generating one or more parametric functions associated with tooth color based on color data from the first region, wherein each of the one or more parametric functions comprises a first variable for a first image axis and a second variable for a second image axis;
- receiving image data comprising new contours of the mouth, wherein one or more of the teeth have a different position in the image data than in the first image;
- determining a second region comprising the teeth in the image data;
- and
- generating a new image based on the image data and the one or more parametric functions, wherein a shape of the teeth is based on the image data and a color of the teeth is based on applying the one or more parametric functions to the second region of the image data.
A system comprising:
- a memory device;
- and
- a processing device operatively coupled to the memory device, the processing device to:
- determine, from a first image of a mouth, a first region of the first image comprising a representation of teeth;
- generate one or more parametric functions associated with tooth color based on color intensity data from the first region, wherein each of the one or more parametric functions comprises a first variable for a first image axis and a second variable for a second image axis;
- receive image data comprising new contours of the mouth, wherein one or more of the teeth have a different position in the image data than in the first image;
- determine a second region comprising the teeth in the image data;
- and
- generate a new image based on the image data and the one or more parametric functions, wherein a shape of the teeth is based on the image data and a color of the teeth is based on applying the one or more parametric functions to the second region of the image data.
