Heaven/TQA Posted August 1, 2012 Share Posted August 1, 2012 here are my attempts. run millions of time. maybe some of you can preprocess the pics better to get more accurate results. amiga_tbl.bmp dragon.bmp Quote Link to comment Share on other sites More sharing options...
ZebCorpse Posted August 1, 2012 Share Posted August 1, 2012 (edited) I think, convener (in the current state) does much better work in the handling pictures with strong color contrast (a few shades of green, red, blue) than ones having fluid color passages (skin tones especially or sky tones etc). So, it manges fairy well typical "pixel" graphics but not so well photographs. Maybe we should "blame" freeimage conversion routines, as well? Proper pre-prepare images for conversion is very important step after all (vide that "famous" hires C64 chick picture). zebcorpse_walking.xex zebcorpse_game.xex zebcorpse_lady.xex zebcorpse_pal.xex zebcorpse_pumpkin.xex zebcorpse_room.xex zebcorpse_samurai.xex Edited August 1, 2012 by ZebCorpse 9 Quote Link to comment Share on other sites More sharing options...
ilmenit Posted August 1, 2012 Share Posted August 1, 2012 I think, convener (in the current state) does much better work in the handling pictures with strong color contrast (a few shades of green, red, blue) than ones having fluid color passages (skin tones especially or sky tones etc). This is caused by Atari limitations itself. You have a very limited number of colors to choose from (4 to in single place of the picture, so you can forget about fluent color passes. If colors are needed somewhere else for better global picture similarity - it may happen that you won't have even a single exact color to choose from. With strong contrast number of colors gets reduced so the output is usually more as expected. Nice pictures by the way :-) Quote Link to comment Share on other sites More sharing options...

Proper pre-prepare images for conversion is very important step after all (vide that "famous" hires C64 chick picture). Hires qualities of the C64 cannot be reached due to the given restrictions. The automation of picture import is rather buggy, so the upper limit of possible colourisation is still to reach. The mistakes start with the used palettes, instead of an indexed colour-set with changeable colour values. The next mistake is to use the double dither, splitted into resize and colour dither. -The good part here: If the colour filter detects a blue and red dither part, it uses a violet of the palette... -The bad part is, it doesn't use red and yellow dither to get an orange colour(for example) So the next mistake is in the importer and the banding.... it produces bandings and tells "it's the best choice" even if several commands are free and used colour were clearly below the limits. The most interesting bug is the "wrong band in the center of a huge unicolour range". Not sure whether it's caused by mistakes in the calculation formulas or in the choicing decision of the converter's creator. And, not to forget the wrong placed colour values of the standard gfx-modes. Ilmenit stated in another post, the decision was to have a "real colour picture importer" so in that point , things were ok. A real picture importer for quality A8 displaying, will still be missing. Big hopes go to Graph2font and some automated code creation while editing a picture. emkay-rambovga450.xex Quote Link to comment Share on other sites More sharing options...

ivop Posted August 3, 2012 Share Posted August 3, 2012 Here are some pictures of Amsterdam. 24M evals 13M evals 20M evals All with laoo palette and chess dithering and /s 1 I have a pretty slow computer, so perhaps somebody could run a couple of hundred million evaluations with better settings 6 Quote Link to comment Share on other sites More sharing options...
RevEng Posted August 4, 2012 Share Posted August 4, 2012 Ali vs Liston. Knoll dithering 0.5 strength, default palette, s=10000, 200k evaluations... RevEng_AliVsListon.xex Mike, are you preparing a 21 Blue A8 version? I won't deny the idea went through my head, but I have too many pots on the stove right now.

Synthpopalooza Posted August 5, 2012 Share Posted August 5, 2012 My latest, originally from this thread: synthpopalooza-enchanted.xex Gave up on it after a few days and 150M evals. I used knoll dithering, laoo palette and knoll dither. Maybe others results will be better. Quote Link to comment Share on other sites More sharing options...
Synthpopalooza Posted August 6, 2012 Share Posted August 6, 2012 Another one, a Gandalf picture from the latest Hobbit movie.

miker Posted August 6, 2012 Share Posted August 6, 2012 Can anyone try to play with this picture? It was preprocessed to 320x200x256 (and apparently don't have so much colors per line) but I constantly fail to make it right (or just don't haave such a fast comp nor enough patience). Thanks!

The colors of this picture do not map well to Atari palette.

miker Posted August 10, 2012 Share Posted August 10, 2012 (edited) Ok Here's some from me: All above from Atari ST games ("Utopia" and "Champion of the Raj") except last one that is from Falcon game "Crown of Creation 3D". All of them are in attached archive as well as two versions of picture that appears as rather Not Safe for Work. Enjoy! Edit: I just noticed that Utopia wasn't displayed correctly, so please re-download attached archive. Hint: if there are some unwanted dashes, point or colors that appear only in .xex file, please let RastaConverter continue for even a few seconds and then save the picture again. IT WORKS! miker_RastaPics.zip Edited August 10, 2012 by miker 1 Quote Link to comment Share on other sites More sharing options...
ZylonBane Posted August 10, 2012 Share Posted August 10, 2012 One would think that by now everyone would have figured out that low-color images aren't exactly the best showcase for this technique. Quote Link to comment Share on other sites More sharing options...
Bryan Posted August 11, 2012 Share Posted August 11, 2012 In my opinion low color images are the ones that have a chance of avoiding streaky artifacts. If we can make the A8 look as good as an ST, that's still a huge step forward. Quote Link to comment Share on other sites More sharing options...
Wrathchild Posted August 11, 2012 Share Posted August 11, 2012 I think this may have been better to try with a two part conversion through Timanthes first, the result is OK but a second image could have been done to try and make the track lines come out more and then combine those two pictures into the master.

Wrathchild Posted August 14, 2012 Share Posted August 14, 2012 I wouldn't mind if someone can perhaps find a better set of options for this picture, I'm sure the A8 can do better... Certainly the sun and reflection lacks detail in the resulting picture and the stones would be better more browny... The original image isn't so detailed but I couldn't find a better one.
