Abstract: Methods of creating a texture for a three-dimensional (3D) model using frequency separation and/or depth buffers are provided. Frequency separation may include splitting one or more images each into higher frequency components (which includes finer details such-as facial pores, lines, birthmarks, spots, or other textural details) and lower frequency components (such as color or tone). Depth buffering may include storing higher frequency components of the images within a depth buffer based on a distance of a corresponding vertex in the 3D model from the camera coordinate system, and then, using the closest pixel to the camera. This pixel likely has a highest amount of sharpness or detail. The lower frequency components can be averaged to account for illumination differences, but because the high frequency components have been separated, detail in the final texture may be preserved. Related devices and computer program products are also provided.
