Abstract

Many challenging problems exist, such as, missing boundary details, misclassifying homogeneous clear areas and the difficulty of dealing with low illuminance regions, in defocus blur detection(DBD). To solve these issues, this paper proposed a dual direction complementary learning network(DDCLNet), via dual direction learning and fusing hierarchical complementary features to obtain high quality results. The network consisted of residual modules, a dual direction complementary decoder subnet(DDCDS) and a fusion correction decoder subnet(FCDS). Residual modules extracted hierarchical features of the source images. DDCDS simultaneously learned clear and blurry information to complement each other. FCDS fused complementary features. In addition, all decoder subnets utilized the supervision mechanism to guide the network to learn efficiently. The F-measure increases by 1.1%, 0.1%, 1.8% on three public datasets than other methods and the detection speed reaches 26.618 fps, which surpasses exiting methods. DDCLNet can effectively dig out the information of the hierarchical features and complementary labels, to obtain high quality detection results fast.
