HSR-Diff: Hyperspectral Image Super-Resolution via Conditional Diffusion Models

no code implementations ICCV 2023 Chanyue Wu, Dong Wang, Yunpeng Bai, Hanyu Mao, Ying Li, Qiang Shen

Despite the proven significance of hyperspectral images (HSIs) in performing various computer vision tasks, its potential is adversely affected by the low-resolution (LR) property in the spatial domain, resulting from multiple physical factors.

Multi-Modal Subjective Context Modelling and Recognition

no code implementations19 Nov 2020 Qiang Shen, Stefano Teso, Wanyi Zhang, Hao Xu, Fausto Giunchiglia

Second, existing models typically assume that context is objective, whereas in most applications context is best viewed from the user's perspective.

Decoder Choice Network for Meta-Learning

1 code implementation arXiv 2019 Jialin Liu, Fei Chao, Longzhi Yang, Chih-Min Lin, Qiang Shen

This work proposes a method that controls the gradient descent process of the model parameters of a neural network by limiting the model parameters in a low-dimensional latent space.
