... there is an explosive growth of screen contents due to ... screen sharing, remote cooperation, and online education.
... screen may be downsampled and compressed. ... At the receiver ... super-resolution (SR) of ... screen content images (SCIs) is ... demanded
... However, image SR methods mostly designed for natural images do not generalize well for SCIs due to the very different image characteristics
... propose a novel Implicit Transformer Super-Resolution Network (ITSRN) for SCISR.
... pixel values at query coordinates are inferred from image features ... and ... aggregate similar neighboring pixel values to the query one.
... proposed ITSRN significantly outperforms several competitive continuous and discrete SR methods for both compressed and uncompressed SCIs.
