Retinex-Based Perceptual Contrast Enhancement in Images Using Luminance Adaptation
In this paper, we propose retinex-based perceptual contrast enhancement in images using luminance adaptation. Strong illumination causes the loss of local details in an image.

Multispectral Demosaicking Using Bilinear Decomposition With Multichannel Structural Regularization
In this paper, a multispectral demosaicking algorithm that builds upon bilinear decomposition of a color image is proposed. The proposed algorithm can be summarized into three parts, where the first part constructs a graph-based measure that confines the

Low-light image enhancement based on improved Retinex-Net
In order to solve the problem of high noise and insufficient feature extraction of Retinex-Net in low-light image enhancement processing, this paper proposes a new network structure. First, the Retinex-Net network was used as the basic model to decompose
