Can the expression coefficients be used for expression retargeting purpose? #17
Description
@fengju514 Great job! I have appreciated your brilliant paper that can output 29D expression coefficients. But I wonder if these expression coefficents could be used for expression retargeting purpose. I have a doubt because these coefficients are for the first 29 principal components of BFM expression space, which dont have a meaning mapping to man-made expression blendshapes, such as left-eye wink, wide-open mouth. Am I right? If I am wrong, could you please tell me how the 29 expression blendshapes should be created? for example, which coeficient should be mapped to left-eye wink?
Any explanation from anyone would be appreciated. Thanks in advance.
Best regards,
Sean
