Our paper of Image Processing and Intelligent systems (IPIS) Lab is published in Optics Express (IF: 3.833). [LINK] Title: CODEN: Combined Optimization-Based Decomposition and Learning-Based Enhancement Network for Retinex-Based Brightness and Contrast Enhancement Authors: Sangjae Ahn, Joongchol Shin, Heunseung Lim, Jaehee Lee, Joonki Paik Abstract: In this paper, we present a novel low-light image enhancement method by combining optimization-based decomposition and enhancement network for simultaneously enhancing brightness and contrast. The proposed method works in two steps including Retinex decomposition and illumination enhancement, and can be trained in an end-to-end manner. The first step separates the low-light image into illumination and reflectance components based on the Retinex model. Specifically, it performs model-based optimization followed by learning for edge-preserved illumination smoothing and detail-preserved reflectance denoising. In the second step, the illumination output from the first step, together with its gamma corrected and histogram equalized versions, serves as input to illumination enhancement network (IEN) including residual squeeze and excitation blocks (RSEBs). Extensive experiments prove that our method shows better performance compared with state-of-the-art low-light enhancement methods in the sense of both objective and subjective measures. |
