智勐,你好,
请教下,1.您在实际使用的时候,有没有把3dmm/或人脸关键点,直接渲染到虚拟3d卡通形象上?
2.您觉得加入文本进行训练,会不会明显提高算法的指标?

你好,请教不敢当哈→_→
1.“将3dmm/或人脸关键点,直接渲染到虚拟3D卡通形象上”是指人脸到卡通的表情迁移吗?这个做过,在卡通模型上手K和3dmm一样的blendshape通道,然后3DMM拟合人脸得到blendshape系数放到卡通形象上,我简单做了一下发现效果不好,需要加正则项调整在人脸landmark上的过拟合程度,然后就没做了。

2.会,使用文本我感觉效果更好,缺点是不能跨语言,之前我们就是用文本做的,可以参考“Write-a-speaker: Text-based Emotional and Rhythmic Talking-head Generation”, 如果驱动口型,可以参考音素驱动的这一篇“a deep learning approach for generalized speech animation”
