fixed model sizes from previous update. avoided bug in ML framework(keras) that forces to train the model on random noise. Converter: added blur on the same keys as sharpness Added new model 'TrueFace'. This is a GAN model ported from https://github.com/NVlabs/FUNIT Model produces near zero morphing and high detail face. Model has higher failure rate than other models. Keep src and dst faceset in same lighting conditions.
