GPSToken: Gaussian Parameterized Spatially-adaptive Tokenization for Image Representation and Generation
Zhengqiang Zhang, Rongyuan Wu, Lingchen Sun +1
Effective and efficient tokenization plays an important role in image representation and generation. Conventional methods, constrained by uniform 2D/1D grid tokenization, are infle…
Generalized and Efficient 2D Gaussian Splatting for Arbitrary-scale Super-Resolution
Du Chen, Liyi Chen, Zhengqiang Zhang +1
Implicit Neural Representations (INR) have been successfully employed for Arbitrary-scale Super-Resolution (ASR). However, INR-based models need to query the multi-layer perceptron…
FreCaS: Efficient Higher-Resolution Image Generation via Frequency-aware Cascaded Sampling
Zhengqiang Zhang, Ruihuang Li, Lei Zhang
While image generation with diffusion models has achieved a great success, generating images of higher resolution than the training size remains a challenging task due to the high…
Spatial-Mamba: Effective Visual State Space Models via Structure-aware State Fusion
Chaodong Xiao, Minghan Li, Zhengqiang Zhang +2
Selective state space models (SSMs), such as Mamba, highly excel at capturing long-range dependencies in 1D sequential data, while their applications to 2D vision tasks still face…
