Innovative research on the visual performance of image two-dimensional animation film based on deep neural network

Deep neural network (DNN) has gone through more than forty years from the simulation stage to the embryonic stage, to the conception and the initial formation of the theory, until further simple applications. Firstly, deep convolution neural network is used to extract features, and then the extracted features are coded by Gaussian aggregation. Finally, the encoded features are input into the full connection layer to classify the image. The experiment in this paper focuses on the two-dimensional facial expression animation technology under DNN. This experiment mainly introduces the two important steps of image conversion, spatial mapping and resampling technology, as well as the detailed definition of the MPEG-4 standard. By using the feature points obtained in the experiment as the feature points set in the face definition parameters, in the deformation algorithm based on Delaunay triangulation, the inverse mapping technology and the quadratic linear interpolation technology are combined with the face and combined with facial animation. The parameter step can realize the conversion of facial expressions, and the generated facial expressions are more natural and delicate.The experimental data show that the facial animation parameters (FAP) as a complete set of basic facial movements can recognize the most subtle facial expressions under DNN. Change, different FAP combinations can form different facial expressions. The experimental results show that the 76 facial feature points located in the experiment have been tested for grid generation. When the segmentation threshold is larger, the merge method is closer to the sub-point insertion method; otherwise, it is closer to the divide and conquer method. When the threshold is 20, the algorithm belongs to the divide and conquer method; when the threshold is 80, the algorithm belongs to the point insertion method. Through research, this article finds that the innovation of DNN on the visual performance of animated films can provide more help for the production of sophisticated animation works, and can continuously improve the visual performance and cultural connotation of animated films.
