Abstract: Regular static convolutions work well for low-frequency information processing but fall short for high-frequency information processing. Dynamic convolution is the recent method that has spatial anisotropy and content-adaptiveness, enabling it to restore complicated and sensitive high-frequency information. The proposed method makes use of dynamic convolution to enhance the learning of multi-scale and high-frequency features. To accomplish this, two blocks - the dynamic convolution block (DCB) and the multi-scale dynamic convolution block (MDCB) are introduced. Dynamic convolution is used by the DCB to improve high-frequency information, whereas skip connections are used to protect low-frequency information. To efficiently extract multi-scale features, the MDCB uses shared adaptive dynamic kernels of increasing size along with dynamic convolution. The proposed multi-dimension feature integration mechanism is used to produce accurate and contextually enriched feature representations. For successful denoising, an improved adaptive dynamic filtering network is useful.
