报告题目:Deep Learning for Visual Synthesis and Manipulation

主持人:程明明(南开大学)


报告摘要:

Realistic image synthesis and manipulation is challenging because it requires generating and modifying the image appearance in a user-controlled way, while preserving the realism of the result. Unless the user has considerable artistic skill, it is easy to "fall off" the manifold of natural images during generation and editing. In this talk, we propose to learn the natural image manifold directly from data using deep neural networks. We then define a class of image generation and editing operations, and constrain their output to lie on that learned manifold at all times. We present three different approaches: (1) Deep discriminative model: we train a discriminative CNN classifier to predict the realism of the generated result, and optimize an image generation pipeline to maximize the predicted realism score; (2) Deep generative model:  we propose to model the natural image manifold directly via a generative adversarial neural network, and constrain the output to be generated by the generative model; (3) Image-to-Image network: we train a network to map user inputs directly to the final results.
