Re: [go-nuts] Golang JPEG2000 implementation / Gauging community interest in supporting it?

[Adam Koszek]

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.

[go-nuts] Golang JPEG2000 implementation / Gauging community interest in supporting it?

[Adam Koszek]

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.

Thanks,

Wojciech Adam Koszek
