WebAug 16, 2024 · Discolouration is also hard to solve because often there's no easy way to differentiate between intended de-saturated areas and compression artifacts. Macro-blocking can be fixed in theory by applying a blur effect. But you have to sacrifice sharpness. Fine artifical noise can be added to gain a bit of sharpness again. WebMar 1, 2024 · To minimize the blocking artefact problem, several researches have been done. But adaptively lacks in those algorithms which leads to complex calculation and distortion in the image.
