【摘要】 本文以高清户外直播技术为切入点，针对夜晚场景下受光照条件限制直播画面亮度低、不清晰的问题，提出了一种基于双路编解码器的卷积神经网络，应用于低照度图像增强和超分辨率，有效提升了户外直播的画面质量，降低了对传输带宽的需求，有利于提升户外直播的用户体验。更多还原

【Abstract】 This paper takes HD outdoor live broadcast technology as research background.In night scenes,live broadcast videos captured under restriction of lighting conditions are unclear and have low brightness.To solve the problem,this paper proposes a convolutional neural network based on dual codec,which can be applied in low-light image enhancement and super-resolution.This network can effectively improve the quality of outdoor live broadcast in night scenes,reduce the demand for transmission bandwidth and help improve user experience of outdoor live broadcast.更多还原
