GLocal: Global Graph Reasoning and Local Structure Transfer for Person Image Generation
This work addresses texture and pose issues in person image generation, which is incremental as it builds on prior methods by adding global reasoning and local transfer.
The paper tackles person image generation under conditions like texture corruption or pose changes by addressing texture occlusion and pose misalignment, resulting in improved occlusion-aware texture estimation and local structure preservation.
In this paper, we focus on person image generation, namely, generating person image under various conditions, e.g., corrupted texture or different pose. To address texture occlusion and large pose misalignment in this task, previous works just use the corresponding region's style to infer the occluded area and rely on point-wise alignment to reorganize the context texture information, lacking the ability to globally correlate the region-wise style codes and preserve the local structure of the source. To tackle these problems, we present a GLocal framework to improve the occlusion-aware texture estimation by globally reasoning the style inter-correlations among different semantic regions, which can also be employed to recover the corrupted images in texture inpainting. For local structural information preservation, we further extract the local structure of the source image and regain it in the generated image via local structure transfer. We benchmark our method to fully characterize its performance on DeepFashion dataset and present extensive ablation studies that highlight the novelty of our method.
