Image Super-Resolution: A Comprehensive Review

Image Super-Resolution aims to enhance the resolution of images using techniques like SRCNN and VDSR. Recent techniques focus on reducing computational power by working in low-resolution space and employing learned upscaling methods. Advanced architectures like EDSR avoid Batch Normalization for better performance and efficiency. Methods like MDSR use shared residual blocks to handle multiple resolutions. GAN-based methods like SRGAN optimize for perceptual quality. The tutorial includes a practical example using ESPCN and TensorFlow, trained on the DIV2K dataset.
