Image enhancement method and system based on Zero-DCE network

The invention provides an image enhancement method and system based on a Zero-DCE network, and the method comprises the steps: employing an improved Zero-DCE network for a to-be-enhanced image, and obtaining a high-order curve corresponding to the mapping of a plurality of pixel-level curve parameters; performing iterative enhancement processing on the to-be-enhanced image by adopting each high-order curve to obtain a final image enhancement result; according to the method, three deconvolution layers are added on the basis of an original network and are respectively embedded among the original three convolution layers, so that the compensation of image detail information is realized, and the image enhancement effect is improved. 本发明提供了一种基于Zero-DCE网络的图像增强方法及系统，对待增强的图像采用改进的Zero-DCE网络，得到多个像素级曲线参数映射所对应的高阶曲线；采用各高阶曲线对待增强的图像进行迭代增强处理，得到最终的图像增强结果；本发明在原有网络的基础上增加三层反卷积层，分别嵌入在原有三层卷积层之间，实现了对图像细节信息的补偿，提高了图像增强效果。
