Degradation-aware adaptive context gated image restoration method and system
By extracting multi-scale degradation features and hierarchical contextual cue vectors, and combining spatial and frequency domain collaborative dual-domain feature modulation and adaptive gating fusion, the problem of degradation artifacts contaminating deep features in existing technologies is solved, achieving high-precision and efficient image restoration.

Abstract
本申请提出了一种退化感知自适应上下文门控图像复原方法及系统。属于图像复原领域，该方法包括从目标图像中提取多尺度退化特征；在编码器的最深层特征上执行空间域与频域协同的双域特征调制，得到增强的瓶颈层特征；在编码器与解码器之间的跳跃连接处，对编码器输出的浅层特征与解码器对应的深层特征进行空间与通道双重门控融合，得到去噪后的跳跃连接特征；在编码器和解码器各层特征处理中，利用分层级上下文提示向量动态调节自注意力机制的温度系数和输出门控，得到注意力增强特征；基于增强的瓶颈层特征、去噪后的跳跃连接特征和注意力增强特征，进行逐级上采样重建，输出复原图像。其能够提升在多种复杂退化场景下的图像复原精度与泛化能力。
