Synthesizing hair features in image content based on orientation data from user guidance

A system comprising:

• a processing device;
• and
• a non-transitory computer-readable medium communicatively coupled to the processing device, wherein the processing device is configured to execute program code stored in the non-transitory computer-readable medium and thereby perform operations comprising:
• accessing guidance data identifying a desired hair feature and an appearance exemplar comprising image data that includes color information for the desired hair feature,
• transforming the guidance data into an input orientation map,
• matching the input orientation map to an exemplar orientation map having a higher resolution than the input orientation map,
• generating the desired hair feature by applying the color information from the appearance exemplar to the exemplar orientation map, and
• outputting the desired hair feature at a presentation device.

A non-transitory computer-readable medium having program code that is stored thereon, the program code executable by one or more processing devices for performing operations comprising:

• accessing guidance data identifying a desired hair feature and an appearance exemplar comprising image data that includes color information for the desired hair feature;
• transforming the guidance data into an input orientation map;
• matching the input orientation map to an exemplar orientation map having a higher resolution than the input orientation map;
• generating the desired hair feature by applying the color information from the appearance exemplar to the exemplar orientation map;
• and
• outputting the desired hair feature at a presentation device.
