Understanding Example Based Super Resolution
Example based super resolution, often referred to as EBSR, is a sophisticated method that leverages a set of high-resolution images as references to enhance the quality of low-resolution images. Unlike conventional approaches that rely solely on mathematical algorithms, EBSR draws inspiration from existing high-resolution images to reconstruct finer details in low-resolution counterparts.
How Example Based Super Resolution Works
EBSR operates on the premise that similar patches of pixels in high-resolution images correspond to similar patches in low-resolution images. By identifying these correspondences, the algorithm extrapolates missing information in the low-resolution image. This process involves learning the relationships between high and low-resolution image pairs, enabling the algorithm to predict and generate high-frequency details.
