I'm already using JP2KAK_THREADS :>> It's nice to know that openjpeg passes the compliance tests. I will be hopefully be using openjpeg in the next couple of months as I'be problems with the change in the Kakadu license and the cost implications with upgrading from 6.4 to the latest. On Tue, 11

Hi, Even's interpretation of the NITF/NSIF standard is correct. My experience is that Jasper reads all NITF test images so does Kakadu. Kakadu is very fast however I've had problems with too many threads being used affecting overall system performance. I've not tried openjpeg for a couple of y

Jukka, Thank you for your response. I can't provide the image, but we're working with 8-band MSI from Worldview-2 so the images are larger than 1024x1024. Given your information, it sounds like compiler flags aren't going to help. Do you think I'll see better performance on these tiles using e

[gdal-dev] JasPer vs OpenJPEG performance

2015-08-07 Thread ewenger
I'm building GDAL 2.0 with JPEG-2000 support for my current project and I was surprised about the performance differences I saw between JasPer and OpenJPEG. Using JasPer, gdal_translate is able to decompress a 465 MB NITF C8 file in 2.3 minutes (wall clock) even though JasPer runs single-threaded.
