Spectral imaging systems

Adaptive grayscale compressive spectral imaging using optimal blue noise coding patterns

This paper proposes an adaptive grayscale coded aperture design which combines the advantages of blue noise and block-unblock coding patterns to provide high-quality image reconstructions and redundancy in the sampling.

Supervised spatio-spectral classification of fused images using superpixels

The proposed approach exploits the spatial information of an RGB image by grouping pixels with similar characteristics into superpixels and fuses such features with the spectral information of an HS image.
