24 alternatives to High End Color Quantizer
This is a personal project I've been working on for a long time now. I stumbled upon the color quantization problem while doing something related for work. I then found an interesting paper for which I could find no implementations online, and the thing went from "let's implement this paper" to getting pretty obsessed with the whole thing. It's at an early, eaaaarly stage. There's a lot of work to be done, and it's a memory hog, but generally speaking works quite well, and the output is for the most part very high quality, so I'm happy to share it as beta.
High End Color Quantizer is a tool that reduces the number of colors in images while maintaining visual quality. It is designed for developers and designers working with color reduction problems. The tool implements… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hi HN, I’m Emil, the maker behind Palette. I’ve been tinkering with AI and colorization for about five years. This is my latest colorization model. It’s a text-based AI colorizer, so you can edit the colorizations with natural language. To make it easier to use, I also automatically create captions and generate filters. Let me know what you think. You can see some of my results on my reddit page: https://www.reddit.com/user/emilwallner/?sort=top

Hey HN, My wife is a designer, and one day she asked me if there was a tool to enhance images and improve their quality. I recommended a few to her, but she found that the suitable ones were too expensive, and the more affordable options didn't offer enough magnification, most only going up to 2x or 4x. So, I thought, why not create a tool that meets her needs, one that can greatly enhance image resolution and clarity while being very affordable to use? After over a month of effort, I finally completed this tool. It can now enlarge images up to 10 times, with a maximum support of 12,000…

Hey! My name is Dima, I am from Ukraine and I am the co-founder of Lost Pixel! We built this tool to solve our problems at work and decided to open-source it so more people can build their custom visual regression testing pipelines! If you want to chat about the tool or visual regression testing in general I am super excited to meet like-minded people! Thanks a lot for checking out the product and I hope it will serve you well if you decide to try it out :D

A simple tool I made over the week to explore and learn about different colors. You can select any color with any opacity #000000-FFFFFFFF (~4.3 billion colors/variants), and you can view a dedicated page detailing the color's closest name, conversions to Hex, RGB, CMYK, etc., shades, tints, tones, harmonies, opacities, and WCAG contrast compliance.

Enlarger▲6Hey everyone! I know there are gazillion alternatives out there especially with AI and all, but this nevertheless is my take on it. I created it because I was frustrated with the options I was seeing in the market. Too heavy, too complex, UX was meh, the output created was not resonating with my style of photography, they are generally glitchy or hallucinate too much, and I dislike subscription fees or credits personally. I prefer BIFL licenses and desktop apps. Since most will probably compare it to the free and open source Upscayl, I went ahead and did a comparison post on the visual…

Hi I am looking for some feedback on our new project "Sketch Colourisation". The envisioned UI and objectives are -- * An artist should have greater control on how to colour a sketch. While a text-to-image model lacks this fine-grained control, a per-pixel colourisation pipeline makes sketch colourisation a laborious process with high-entry barrier. * What if an artist only draws a mask for a local region and specifies the colour palette for that local region? Then a neural network figures out how to colour the overall sketch -- while maintaining those local colour palette. [I would really…

hey there hn! thought you would appreciate my brand new file format - i've spent over 40 minutes creating this standard. it's really hard trying to get your ideas shown to standards boards etc but i think with the great community here we can help get bioif support into all major browsers :) the spec is available over at the website, as is a reference implementation. it already has higher usage than jpeg-xl. - best
