Fig. 6: Structure and performance of USRNN.

a The network structure diagram of the USRNN used for super-resolution restoration, capable of achieving 2x or 4x resolution reconstruction. b The comparison of the 2x resolution reconstruction effects between the USRNN based on hardware-software co-design and other software methods within the same image. c and d The demonstration of the effectiveness of the USRNN for 2x and 4x resolution reconstruction. e The PSNR and SSIM indices obtained for each image in Fig. 6b. f The performance of the USRNN for 2x and 4x resolution reconstruction across multiple training cycles.
