Spectral Super-Resolution for High Dynamic Range Images
The images we commonly use are RGB images that contain three pieces of information: red, green, and blue. On the other hand, hyperspectral (HS) images retain wavelength information.

Image Relighting Network Based on Context-gated Residuals and Multi-scale Attention [PDF]
Image relighting is commonly used in image editing and data augmentation tasks.Existing image relighting methods suffer from estimating accurate shadows and obtaining consistent structures and clear texture when removing and rendering sha-dows in complex

What image features guide lightness perception? [PDF]
Lightness constancy is the ability to perceive black and white surface colors under a wide range of lighting conditions. This fundamental visual ability is not well understood, and current theories differ greatly on what image features are important for ...

Multiscale Retinex Application to Analyze Face Recognition
The main challenge that facial recognition introduces is the difficulty of uneven lighting or dark tendencies. The image is poorly lit, which makes it difficult for the system to perform facial recognition.
