4.2.2. Effect of AGFAN

Table 6 shows the ablation study results on AGFAN. In this experiment, we compare the detection results in the network with and without alignment module, respectively. The two networks used in the experiment are completely consistent, except for the alignment module. One network contains AGFAN, while the other does not. Both networks contain BAFPN and the task decoupling module in RDN. As can be seen from Table 6, the network with the alignment module has a higher detection accuracy. This is because the alignment module adjusts the sampling points of the network according to the rotated anchors. This enables the network to extract features according to the guidance of the anchor and reduces the dislocation caused by the use of rotated anchors. The '✔' Table 6 means with AGFAN, and the '**- -**' means without AGFAN.
