NTIRE 2024 challenge on spectral reconstruction from an RGB …
WebHS dataset, it is more convenient to obtain many HS im-ages. Recent years have witnessed various studies includ-ing sparse coding and deep learning. In 2008, Parmar et al. [27] proposed a data sparsity expanding method to recover the spatial spectral data cube. Arad et al. [3] first lever-aged HS prior in order to create a sparse dictionary of HS Webhybrid RGB-HS systems [16] and others. In this challenge we focus on one of the more recent approaches: the recov-ery of visual-spectrum ‘hyperspectral’ images from RGB-only input.

Capturing visual image with a hyperspectral camera has been successfully applied to many areas due to its narrow-band imaging technology.

The whole HRNet is trained for 10000 epochs overall. The initial learning rate is . 1 × 10 − 4 and halved every 3000 epochs. For optimization, we use Adam optimizer with β 1 = 0.5, β 2 = 0.999 and batch size equals to 8. check attribute python
