Cannot generate realistic facial images when using hand-drawn sketches.

[nexuslrf]

Hi, I recently tested this model by using some hand-drawn sketches (rather sketches by sketch generators). I found the generated images look much worse than using generated sketches.

For example when the input sketch is

Your model will just output such an immature unrealistic facial image.

To make sure this is not the problem with my drawing, I also tested the sketches shown on your paper (e.g., Fig. 15). The generated results are still much worse than the ones shown on the paper.

For example, this sketched head shown in Fig. 15

generates the face below,

this is completely different from the results in Fig. 15.

Could you please explain why such differences exist, and how to generate the correct images.

Thanks in advance.
