The Degree of Linear Polarization (DoLP) is a key dimension of information in polarization imaging. The quality of polarization images is greatly affected by imaging equipment and environmental factors. Therefore, an enhancement method for the DoLP image is proposed in this paper. First, a super-resolution reconstruction algorithm based on the Detail Enhancement Guided Image Filter is proposed to solve the problem of mosaicization and pseudo-polarization information caused by the degradation of spatial resolution and super-resolution reconstruction of DoFP imaging. Second, for the problem of rapid degradation of polarization image quality caused by hazy environment, a DoLP enhancement algorithm based on multi-channel difference Signal-to-Noise Ratio is proposed to improve the visual effect of polarization images in different scenes with hazy environment. The method proposed in this paper implements super-resolution reconstruction, demosaicing, pseudo-polarization information removal, and adaptive enhancement of DoLP images in DoFP systems.

Due to the low spatial resolution of the existing optical micro-scanning thermal microscope imaging system, the acquired micro-scanning infrared images have inferior image quality and low contrast. Deep learning methods, represented by SRGAN, have shown promising results in super-resolution. However, this method still has artifacts, blurriness, low spatial resolution, and slow reconstruction speed. Therefore, we propose the SMC-SRGAN-Lightning super-resolution algorithm based on optical micro-scanning thermal microscope images in this study. Firstly, we enhance the model’s attention to features and improve the details and clarity of the reconstructed images. Removing the BN layer in residual blocks, replacing the ReLU with SMU, and introducing the CBAM to construct the SMC module. Secondly, we incorporate the attention mechanism SEnet into the Bottleneck structure of MobileNetV2. Reducing the channels in the first 1 × 1 convolution layer to 1/4 and creating the SE-MobileNetV2 module. It can enhance the model’s focus on essential features, computational efficiency, and accuracy. Finally, to validate the effectiveness of our method, we compare it with four other super-resolution algorithms on public datasets and images obtained from the optical micro-scanning thermal microscope imaging system. Experimental results indicate that our method improves image clarity, preserving details, and textures. Comprehensively considering super-resolved image quality and time costs, our method is superior to other methods. [ABSTRACT FROM AUTHOR]
