In the study, we developed a high dynamic range (HDR) reconstruction method based on attention and feedback mechanism. First, three continuous frames with cyclic exposure were captured as the input of the network. The attention image was generated by introducing the attention module, and the acquired features were weighted adaptively to optimise the feature extraction of the network and reduce ghost phenomenon occurrence. Subsequently, the feedback mechanism was introduced into the network to improve the efficiency of feature information further and optimise the network performance in feature fusion and reconstruction. Finally, based on the L1 loss function, the proposed network added colour similarity and VGG loss functions to enhance the colour similarity and reconstructed HDR image details. The experimental results show that the proposed HDR reconstruction method based on attention and feedback mechanism can achieve better subjective and objective reconstruction quality and is superior to the existing mainstream algorithm.
