anybody know how to turn an old scan like this into only black on white? Is there a good AI that can do it now? Pic is just an example
Good, turn high res scans into AI slop. Introducing nonsense in the process. The original high res scans of course will become lost media. Man, I hate AI cultists so much.
>>1577453My Photoshop build from 2007 can do that. Just adjust the levels man
>>1577453It's a surprisingly difficult subject. I remember reading https://askubuntu.com/questions/396437/how-can-i-remove-the-gray-scale-page-background-of-a-pdf-document-scan-while-pre and other threads. Tried all the possible solution, and all of them involve too many manual work + abandioned softwares.
>>1577484The best case scenario is when it's all text and black and white. Good scans, like on ia, will have layers that are already separate the yellow/gray background and the text and the shadows. The separation isn't perfect though. Images and logo will be ruined if you only keep the text layer. Basically this method, threshold, and others will not produce perfect result.
>>1577453Just play with the settings in the 'threshold' color tools of Photoshop/GIMP/Paint.NET/pretty much any image editor and you can get something decent pretty quickly.
>>1577480>>1577496thanks, I played with the histogram then threshold and got this. I also sharpened a little. Wish there was a way to fill in the gaps of white inside black areas, like the notes, but this is good enough
Using just the image viewer program IRFANVIEW, I did the following:1. Image Pulldown menu --> convert to grayscale2. Image Pulldown menu --> decrease color depth 163. Image Pulldown menu --> decrease color depth - custom 84. Shift U5. Image Pulldown menu --> decrease color depth - custom 46. Image Pulldown menu --> decrease color depth - custom 37. Image Pulldown menu --> decrease color depth 2There were so many steps since I simply "nibbled" my way along experimentally (out of curiousity) without trying to improve the method with fewer steps.
>>1577548I did this through Google Gemini. It originally changed the fucking timing to 3/2. It might have fucked up other things, too.
>>1577633Not the OP but I actually played this piece for fun.Well done anon.
>>1577633OP here. dang, surprised Gemini did that good of a job. Hopefully it will be able to make accurate mxml files from images soon
