[4G2-GS-2k-05] Homogeneous responsive activation function "Yamatani Activation" and application to single-image super-resolution
Keywords:Single image super resolution, Homogeneous responsiveness
When this is used for single-image super-resolution, it is possible to achieve super-resolution that is independent of the dynamic range of the image and that responds homogeneously to differential components. In order to verify the usefulness of this property, we created artificial images with various edge patterns, trained a neural network with these images, and verified whether this neural network can also super-resolve real images. As a result, PSNR:32.56, SSIM:0.915 were achieved in RGB 3-channel evaluation condition, DIV2K, x2.
