Abstract
A three-dimensional (“3D”) avatar can be automatically created that resembles the physical appearance of an individual captured in one or more input images or video frames. The avatar can be further customized by the individual in an editing environment and used in various applications, including but not limited to gaming, social networking and video conferencing.
Claims20
A computer implemented method, comprising:
- receiving one or more digital images of an individual;
- determining, in a computer, digital representations of facial elements of the individual from the one or more digital images;
- searching a population of avatars using a genetic process, where the genetic process includes using the computer to evaluate the overall fitness of the avatars using a fitness function that compares the digital representations of the individual's facial elements to digital representations of corresponding avatar facial elements;
- and
- selecting or receiving a selection of one or more avatars from the population of avatars based on fitness values associated with the avatars;
- wherein evaluating the overall fitness of the avatars using a fitness function includes calculating fitness values for individual facial elements of the avatars based on linear and geometric weights corresponding to each of the individual facial elements.
A system, comprising:
- a processor;
- and
- a computer-readable storage medium coupled to the processor and including instructions, which, when executed by the processor, causes the processor to perform operations comprising:
- receiving one or more digital images of an individual;
- determining, in a computer, digital representations of facial elements of the individual from the one or more digital images;
- searching a population of avatars using a genetic process, where the genetic process includes using the computer to evaluate the overall fitness of the avatars using a fitness function that compares the digital representations of the individual's facial elements to digital representations of corresponding avatar facial elements;
- and
- selecting or receiving a selection of one or more avatars from the population of avatars based on fitness values associated with the avatars;
- wherein evaluating the overall fitness of the avatars using a fitness function includes calculating fitness values for individual facial elements of the avatars based on linear and geometric weights corresponding to each of the individual facial elements.
A non-transitory computer-readable storage medium having instructions stored thereon, which, when executed by one or more processors, causes the one or more processors to perform operations comprising:
- receiving one or more digital images of an individual;
- determining, in a computer, digital representations of facial elements of the individual from the one or more digital images;
- searching a population of avatars using a genetic process, where the genetic process includes using the computer to evaluate the overall fitness of the avatars using a fitness function that compares the digital representations of the individual's facial elements to digital representations of corresponding avatar facial elements;
- and
- selecting or receiving a selection of one or more avatars from the population of avatars based on fitness values associated with the avatars;
- wherein evaluating the overall fitness of the avatars using a fitness function includes calculating fitness values for individual facial elements of the avatars based on linear and geometric weights corresponding to each of the individual facial elements.
