Three-dimensional model generation

A method for determining a pixel value of a texture pixel associated with a three-dimensional (3D ) scan of an object, the method comprising:

• selecting a first image frame from a sequence of image frames after receiving the sequence of images, the first image frame having a first quality metric value, the first image frame depicting a particular texture pixel from a first angle;
• determining a first pixel value of the particular texture pixel in the first image frame;
• selecting a second image frame from the sequence of image frames, the second image frame having a second quality metric value that is higher than the first quality metric value, the second image frame depicting the particular texture pixel from a second angle;
• modifying the first pixel value based on a second pixel value of the particular texture pixel in the second image frame to generate a first modified pixel value of the particular texture pixel;
• selecting a third image frame from the sequence of image frames, the third image frame having a third quality metric value that is higher than the second quality metric value and higher than the first quality metric value, the third image frame depicting the particular texture pixel from a third angle;
• and
• modifying the first modified pixel value based on a third pixel value of the particular texture pixel in the third image frame to generate a second modified pixel value of the particular texture pixel.

A non-transitory computer-readable medium comprising instructions for determining a pixel value of a texture pixel associated with a three-dimensional (3D ) scan of an object, the instructions, when executed by a processor, cause the processor to perform operations comprising:
