Summary: The algorithm proposed an efficient low-light image enhancement by estimating gamma correction parameters through optimization, separating luminance and chrominance channels, normalizing the luminance channel with a logarithmic function, independently estimating optimal gamma parameters for dark and bright regions, and merging them for enhanced image. This approach demonstrates higher enhancement performance and speed improvement compared to state-of-the-art algorithms in both subjective and objective evaluations.

Summary: In this letter, a method is proposed to address the degradation issues of underwater captured images. It uses piecewise color correction and dual prior optimized contrast enhancement. The method corrects the color cast of each color channel and enhances the contrast and texture detail of underwater images by decomposing the base layer and detail layer in HSV color space. Experimental results show that the method outperforms eleven state-of-the-art methods and has good generalization capability for fog and low-light images.

Summary: This study constructs two optimization models for the omnichannel closed-loop supply chain by leveraging the combined power of leader-follower game and mean-variance theories. The focus is on analyzing the performance of manufacturers who distribute products through physical stores. The results show that the risk-averse attitude of the physical store has a positive impact on the overall system profitability, but if the introduced physical store belongs to another firm, total profit experiences a decline.
