Abstract
A computer implemented method of generating a new three-dimensional morphable model (3DMM) by combining a first 3DMM with a second 3DMM includes generating, using the first 3DMM, a plurality of first shapes, calculating a mapping from a plurality of second parameters of the second 3DMM to a plurality of first parameters of the first 3DMM, generating, for each of a plurality of second shapes generated using the second 3DMM, a corresponding first shape, forming a plurality of merged shapes by merging each second shape with the corresponding first shape, and performing principal component analysis on the plurality of merged shapes to generate the new 3DMM.
Claims20
A method comprising:
- obtaining a first three-dimensional morphable model (3DMM);
- calculating a mapping from a plurality of second parameters of a second 3DMM to a plurality of first parameters of the first 3DMM;
- generating, using the second 3DMM, a plurality of second shapes;
- generating, for each of the second shapes, a corresponding first shape using the first 3DMM;
- forming a plurality of merged shapes by merging each of the second shapes with the corresponding first shape;
- and
- performing a principal component analysis on the merged shapes to generate a new 3DMM.
An apparatus comprising:
- one or more processors;
- and
- a memory coupled to the one or more processors and configured to store computer readable instructions that, when executed by the one or more processors, cause the apparatus to:
- obtain a first three-dimensional morphable model (3DMM);
- calculate a mapping from a plurality of second parameters of a second 3DMM to a plurality of first parameters of the first 3DMM;
- generate, using the second 3DMM, a plurality of second shapes;
- generate, for each of the second shapes, a corresponding first shape using the first 3DMM;
- form a plurality of merged shapes by merging each of the second shapes with the corresponding first shape;
- and
- perform a principal component analysis on the merged shapes to generate a new 3DMM.
A computer program product comprising instructions stored on a non-transitory computer-readable medium that, when executed by one or more processors, cause an electronic device to:
- obtain a first three-dimensional morphable model (3DMM);
- calculate a mapping from a plurality of second parameters of a second 3DMM to a plurality of first parameters of the first 3DMM;
- generate, using the second 3DMM, a plurality of second shapes;
- generate, for each of the second shapes, a corresponding first shape using the first 3DMM;
- form a plurality of merged shapes by merging each of the second shapes with the corresponding first shape;
- and
- perform a principal component analysis on the merged shapes to generate a new 3DMM.
