Understanding Image Super-Resolution

 

Super-Resolution (SR) in the realm of digital imagery signifies the process of enhancing the resolution of an image. This enhancement, often termed as upsampling, involves increasing the pixel density of an image, thereby augmenting its clarity and detail. The journey from a low-resolution (LR) image to a high-resolution (HR) one is achieved through various sophisticated methods, predominantly leaning on the principles of machine learning and more specifically, deep learning.

In the domain of SR, two primary categories exist: Single-Image and Multi-Image Super-Resolution. Single-Image SR deals with enhancing the resolution of an individual image, often plagued by the emergence of artificial patterns due to the limited input information. This can lead to inaccuracies, particularly in sensitive applications like medical imaging where precision is paramount. On the other hand, Multi-Image SR utilizes multiple LR images of the same scene or object to map to a single HR image, typically yielding better performance due to the richness of information available. However, this method is often hampered by its higher computational demands and practicality issues in obtaining multiple LR images.

The evaluation of SR methods transcends mere visual assessments due to the subjective nature of such evaluations. Universal quantitative metrics like Peak Signal-to-Noise Ratio (PSNR) and Structural SIMilarity (SSIM) Index are thus employed to objectively measure and compare the performance of various SR methods.

Different strategies in image SR mainly revolve around the techniques of upsampling used to achieve the final HR output.
