Embodiment Construction
[0045] The present invention is described in further detail below in conjunction with accompanying drawing:
[0046] Such as figure 1 As shown, the present invention includes a deep learning module, a three-dimensional reconstruction module, a video preprocessing module, a two-dimensional image generation module, and a video editing module.
[0047] 1. Before the user uses the system, the deep learning module trains the convolutional neural network through virtual photos. This training step happens in the background and is only required once. Deep learning requires a large amount of data for training, and large-scale face databases do not exist, so we first need to generate a large number of virtual face databases with the help of existing small databases. Specific steps include:
[0048] A. Virtual photo generation: With the help of the existing small 3D face database, a large number of virtual photos are generated by mapping each 3D model from 3D to 2D under different ang...
