Application of SRGAN to enhance simulations of 2D distribution of dark matter in the Universe.
This code takes LR image of size 128^2 and generates SR image of size 512^2. HR is the ground truth high-resolution image, ILR is the interpolated LR image to 512^2 resolution.
The example below was obtained after 15-hour training on one A100.
Fig. 1. Top: LR, ILR. Bottom: SR, HR. Magenta line defines skewer which passes through the brightest pixel on the HR image.
Fig. 2. Pixel intensity along the skewer.
Fig. 3. Denisty histogram and power spectrum. Top: absolute, bottom: relative.
