Fine-Grained Side Information Guided Dual-Prompts for Zero-Shot Skeleton Action Recognition

no code implementations11 Apr 2024 Yang Chen, Jingcai Guo, Tian He, Ling Wang

However, previous works focus on establishing the bridges between the known skeleton representation space and semantic descriptions space at the coarse-grained level for recognizing unknown action categories, ignoring the fine-grained alignment of these two spaces, resulting in suboptimal performance in distinguishing high-similarity action categories.

Then, to facilitate the generalization of local linearities, we construct a maximal margin geometry on the learned features by enforcing low-rank constraints on intra-class samples and high-rank constraints on inter-class samples, resulting in orthogonal subspaces for different classes and each subspace lies on a compact manifold.

FreePIH: Training-Free Painterly Image Harmonization with Diffusion Model

no code implementations25 Nov 2023 Ruibin Li, Jingcai Guo, Song Guo, Qihua Zhou, Jie Zhang

Specifically, we find that the very last few steps of the denoising (i. e., generation) process strongly correspond to the stylistic information of images, and based on this, we propose to augment the latent features of both the foreground and background images with Gaussians for a direct denoising-based harmonization.
