The architecture of the detecting neck is also depicted
in Figure 3 which comprises a conventional feature pyramid

Recognition Face
Through multilayer perceptron architecture and path
consolidation [13] network, the front segment of the
network achieves the full fusion of low-level features and
high-level features to build rich feature maps, which can
identify the most happening more often instances. However,
for low-resolution photographs, feature fusion cannot
improve the original information of the image, and after
layers of iteration, the prior knowledge of small faces is still
lacking. To boost the recognition rate of small faces in low-
resolution pictures, SR is fused in the detection head
component of the system. For the grid to be computed, the
area data is entered into SRGAN to carry out high-level
functional reconstruction and face detection again through
its coordinate information. Finally, the output of the two-
