Re: [go-nuts] Golang JPEG2000 implementation / Gauging community interest in supporting it?
We're trying to do the same - when we encounter a JPEG2000 encoded file, we convert it. Yet we don't want to keep a converted copy because often people want to see the data in the original form. So right now we got a commercial DICOM codec with the capability of reading / compressing JPEG2000 DICOMs, but it's a hack. We're fork a process and read converted bytes from STDIN. Go implementation would be much, much nicer. On Fri, Nov 5, 2021 at 3:43 AM Nick wrote: > > Hi Wojciech, > > Quoth Adam Koszek: > > I know it's rather a rare format, yet it's "the standard".

There are several open source Java encoder/decoder libraries.

Yeah, in my work on OCR of historical books for rescribe.xyz we come across JPEG 2000 scans every so often, and having native support in Go for it would potentially be handy. That said, massive lossless images are not useful for the use case anyway, so at the moment just converting them to regular JPEGs using ImageMagick before processing works just fine. So consider me an interested party, but not to the extent of being able to offer much in the way of developer time to the endeavour. Cheerleading and testing, though, that much I can happily offer :) Nick -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] Golang JPEG2000 implementation / Gauging community interest in supporting it?
Hello, We (Segmed.ai) are processing a lot of medical imaging data. It comes to us in the form of PNG/JPG/DICOM files. 90% of it is uncompressed or using a normal JPEG encoding, but around ~7% of it is encoded with lossless JPEG 2000 format. We use Suyash Kumar's library: https://github.com/suyashkumar/dicom which depends on the Golang "image/jpeg" library. We'd love to get "image/jpeg" to support JPEG 2000 lossless encoding format. I know it's rather a rare format, yet it's "the standard". I wonder if there are any other users interested in getting JPEG 2000 supported natively in Go? Or maybe someone out there has its implementation written, and would need hand open-sourcing it? I was thinking that maybe there are companies that would benefit from it, and we could co-sponsor someone to whip a nice implementation for us. We could probably help with organizing this, pitch in some $$$ too, and manage the work. In case you're a domain expert in search of a cool project, feel free to reply to this post.
