Ideally, these should be replaced with the same pattern but at the new high resolution.<br />So an enhancement algorithm could look like this:<br />- find all regions with a dithered pattern<br />- rewrite these regions with a higher resolution pattern (with the same colors)<br /><br />This would address only the areas of the map which are dithered and would leave the others unchanged.<br />Maybe xBRZ could be used for the remaining parts? Thus artificially increasing sharpness where it is useful to do so (areas with higher detail density).<br />Laurent Giroudhttps://www.blogger.com/profile/05869545668215870056noreply@blogger.comtag:blogger.com,1999:blog-6140632138569689510.post-50286539232394113612018-03-21T08:44:28.226-07:002018-03-21T08:44:28.226-07:00xBRZ looks really ugly in my view, it is as if the...xBRZ looks really ugly in my view, it is as if the pixels were maimed and merged together.<br />Ideally you would want an algorithm which would add information to the image without denaturing it. I would definitely look into training a neural network to do that. With a good framework this would not require too much work.<br /><br />I suppose that you must not have the original curves used to generate the maps otherwise obviously you could regenerate them with a higher resolution and/or different textures?<br /><br />I will keep thinking about it and will comment again if I get any idea. ;)Laurent Giroudhttps://www.blogger.com/profile/05869545668215870056noreply@blogger.comtag:blogger.com,1999:blog-6140632138569689510.post-2546100642911832552015-03-28T18:40:34.374-07:002015-03-28T18:40:34.374-07:00Pixel-art rescaling on dithered stuff looks quite ...Pixel-art rescaling on dithered stuff looks quite horrible, IMHO. Why not trying some CRT emulation, ideally something really well made, not just lousy scanlines...<br /><br />One could write a quite accurate emulator of the CRT grid and distortion, run it at very high resolution and downscale, maybe, to get something that would look like a photo of a CRT screen...<br /><br />http://www.tested.com/tech/gaming/2982-a-link-to-the-past-how-to-add-crt-filters-to-16-bit-games-on-pc/<br />DEADC0DEhttps://www.blogger.com/profile/01477408942876127202noreply@blogger.com
