“…To evaluate the performance of the proposed B-FEN model, we conduct the experiments on our IVIPC-DQA database. Due to the absence of specific quality metric for de-rained image, we compare the proposed B-FEN model with our previous B-GFN [16] and some representative general-purpose image quality assessment models, which include 10 opinion-aware (OA) metrics (i.e., BIQI [18], BLIINDS II [41], BRISQUE [22], DIIVINE [21], M3 [42], NFERM [43], TCLT [19], MEON [31], DB-CNN [32] and WaDIQaM [33]), and 4 opinion-unaware (OU) metrics (i.e., NIQE [44], ILNIQE [45], QAC [46], and LPSI [47]). Meanwhile, two popular unidirectional feature embedding networks, i.e., DenseNet-161 [37] and ResNet-152 [48] are also involved in our comparison, which are categorized as OA metric in the following section.…”
