Re: [science-iwg] Java Advanced Imaging

[Marc Vloemans <marc.vloemans@xxxxxxxxxxxxxxxxxxxxxx>]

Hi All,

I am following this discussion with interest.

Reg Raster Processing: at the moment within LocationTech we are surveying various RP-initiatives (one from a standardization perspective, one to replace JAI, one being brought in by new member).

As it stands now, it is a matter of 'who has the pain', 'what is the urgency', 'what would a RP-project encompass' and 'what does it cost'.

I can give an update from LocTech side upcoming SC-meeting.

Cheers, Marc

On a side note, we've always been open to including a good imaging capability in EAV. We included the capability in our proposal and we talked several times with the LocationTech people about doing this. It has never gone anywhere and I've stopped trying to get it funded internally at ORNL. I would still be happy to see contributions from the community though. I think it is a critical capability and a terrible whole in the open source market, at least for Java.

Triquetrum is based on Ptolemy II and Ptolemy II has actors that use JAI.  These JAI actors could be used in Triquetrum without much effort if JAI is installed.  We intend to ship JAI with the Ptolemy II release later this year.

However, we don't have much use these days of the JAI actors. These days, we are using OpenCV, which has a Java interface and a _javascript_ interface.  Installing OpenCV tends to be a bit tricky, but the _javascript_ interface via node works OK under Mac, sometimes works under Linux and is tricky to install under Windows.

Hi Torkild,

We have a dependency on its IO library and also another SPI jar from TidalWave for loading certain TIFFs. See https://github.com/DawnScience/scisoft-core/tree/master/uk.ac.diamond.scisoft.analysis/jars

I see http://openjdk.java.net/jeps/262 brings some of that to the JDK. We haven't assess what impact this will have yet. But for imaging processing, there is BoofCV.

Regards,

Subject: [science-iwg] Java Advanced Imaging

Hi all,

At the Architecture Council meeting today[1] we had a short discussion regarding Java Advanced Imaging which is no longer available. The LocationTech people are sorely missing this library and are looking for solutions. I think I remember some Science projects using it. Is this correct? If so, maybe we can try to figure out a solution working with LocationTech.

Best regards,
Torkild
