- Abstract: Single image deraining is a crucial problem because rain severely degenerates
the visibility of images and affects the performance of computer vision tasks
like outdoor surveillance systems and intelligent vehicles. In this paper, we
propose the new convolutional neural network (CNN) called the wavelet channel
attention module with a fusion network. Wavelet transform and the inverse
wavelet transform are substituted for down-sampling and up-sampling so feature
maps from the wavelet transform and convolutions contain different frequencies
and scales. Furthermore, feature maps are integrated by channel attention. Our
proposed network learns confidence maps of four sub-band images derived from
the wavelet transform of the original images. Finally, the clear image can be
well restored via the wavelet reconstruction and fusion of the low-frequency
part and high-frequency parts. Several experimental results on synthetic and
real images present that the proposed algorithm outperforms state-of-the-art
methods.
