AI Technical Summary
Existing text image super-resolution methods struggle to fully extract important features when processing low-resolution text images in the real world, resulting in low recognition rates. Furthermore, conventional methods fail to effectively simulate complex degradation scenarios in the real world.
A dual-branch network for perceiving multiple features is constructed, including a super-resolution branch and a text recognition branch. Visual and text features are fused through an image-image fusion module, a frequency-spatial perception module, and a text-image fusion module. Features are learned in the frequency and time domains, and training is performed using image reconstruction loss and text recognition loss.
It improves the super-resolution reconstruction effect of real-world text images, enhances the perception ability of visual features and text sequence knowledge, and improves the accuracy of text recognition.
