Self-supervised cycle-consistent learning for scale-arbitrary real-world single image super-resolution

作者:

Highlights:

• We propose a self-learning-based scale-arbitrary SR method for real-world images.

• Scale-arbitrary SR and resolution-degradation networks are jointly optimized.

• The cycle consistency, bicubic interpolation, and total variation losses are adopted.

• We enable a parameter to adjust perceptual quality to satisfy users’ preferences.

• Extensive experiments are conducted to demonstrate the effectiveness of our method.
