Abstract
Many networks are designed to stack a large number of residual blocks, deepen the network and improve network performance through short residual connec-tion, long residual connection, and dense connection. However, without consider-ing different contributions of different depth features to the network, these de-signs have the problem of evaluating the importance of different depth features. To solve this problem, this paper proposes an adaptive densely residual net-work (ADRNet) for the single image super resolution. ADRN realizes the evalua-tion of distributions of different depth features and learns more representative features. An adaptive densely residual block (ADRB) was designed, combining 3 residual blocks (RB) and dense connection was added. It learned the attention score of each dense connection through adaptive dense connections, and the at-tention score reflected the importance of the features of each RB. To further en-hance the performance of ADRB, a multi-direction attention block (MDAB) was introduced to obtain multi-directional context information. Through comparative experiments, it is proved that theproposed ADRNet is superior to the existing methods. Through ablation experiments, it is proved that evaluating features of different depths helps to improve network performance.
