LMCAN: A Lightweight Multiscale Contextual Attention Network for Hyperspectral and Multispectral Image Fusion

Hyperspectral and multispectral image fusion requires enhancing spatial details while preserving the pixel-wise spectral fidelity of hyperspectral observations. Transformer-based approaches provide effective contextual modeling, yet hierarchical token merging may cause spectral mixing, whereas pixel-preserving tokeniza...

Tree-Structured Vector Quantization For Efficient And Progressive Image Compression

Tree-VQ is proposed, a progressive tree-structured vector quantization framework for learned image compression that codes progressive continuation decisions and routed branch refinements using only causally available decoded contexts and achieves a superior performance--efficiency trade-off.
