Hi, Could someone please provide the setting that could generate the best quality HD (720 and 1080) MJPEG2000 file using kdu_v_compress? Thanks. Jay...
Hi Guys, I am trying to compress losslessly DICOM images, using kdu_stripe_compressor. I load pixel data into memory buffer and pass it to the compressor. Here...
I want to develop an application in which multiple-bitrate Jpeg2000 data is created from single Jpeg2000 compressed data which has multiple-bitrate quality...
Hello all, We have a situation where some of our compressed images are specified to have ROIs. We also have a size limit for the compressed output image, so...
I found out that the unsigned 16-bit pixels (little endian) are not ranging from 0-65535, but from 30962-33005 only. So only a subset of the 16-bit value range...
Hi: We'd like to by your Non commercial lisence which can research and test the efficiency of HD video codec!Can you give us more information about the Non...
Currently I am in the research phase of a project to understand how NITF2.1 images containing JPEG2000 images can be served from a server to a client. To...
I'm using the Ckdu_region_decompressor object in the managed extensions in VS2005 VC++ .NET to decompress a single channel, signed raw file that had been...
Hi All, The requirment is to produce one jpeg2k video clip with one image, who can give me one hand to resolve it quickly , thanks advancely! Best Regards, ...
We have been trying to track down crashes that seem to occur when using Kakadu to read and write multiple JPEG2000 images in a sequence. This occurs during...
... I'm wondering why the tile-part header of the second codestream needs to be stripped off? Why not: Y_SOT Y_SIZ Y_SOT Y_SOD Y_DATA CrCb_SOT CrCb_SOD...
Hello all, I am a V5 user of Kakadu software. I would like now to move to V6 with speed pack, but before buying the licenses, I would like to test this pack...
I have the latest version of Kakadu, and when I try to run kdu_expand.exe on a file with spaces I get an error. I have put a file (image2.jp2) into the...
Hi, has anybody seen a popup window like this : Assertion Failed! File: kdu_threads.h Line: 176 Expression: group == NULL I have embedded Kakadu 6.0 in my...
Hi, When I tried to decompress & play MJ2 file with kdu_vex_fast command, I got an error,"could not create DirectX display device". the command I tried was; ...
Hi Yas, Try using "W30" first instead of "F30" since the W variant does not require full screen mode. Still, that might not help. This demo executable uses...
Hi Alvin, I'm afraid Kakadu does not contain any explicit DICOM support of its own. It is something that we should definitely consider, although it could be...
Hi Sven, As suggested in the comments with that function, it is best if you call the "destroy" function explicitly first, so that you can check if there is any...
This has nothing to do with Kakadu; it is your usage of the command shell you are using. Surround the file name in double quotes, as in kdu.expand.exe -i...
I suggest that you directly contact Michael D'Aprix outlining what you would like to test and for what purpose. We can go from there. I have CC'd Michael on...
You are right, you should keep the tile-part headers. However, if the tile-part headers do not contain tile-part lengths (i.e., the length field is 0), you...
Dear David Thanks for the reply. I am assuming that you have previous experience in DICOM image streaming. We are planning to develop a Medical Image Web...
In all honestly, this seems to be an issue outside the realm of Kakadu. Applying the window width and level (in terms of grayscale images) is simply a...
I'm using c++ on linux and I want to compile and build The entire kakadu folder. The compiler i'm using is clearcase. What should be in my makefile and where...
You should read the "Compiling_Instructions.txt" file first. It tells you where you can find the make files, what order to build in, what environment...
Hi David, my application uses several threads that loads images and process them. I am not exclusively using JPEG2000. I wrote a new import function for...
I am wanting to perform lossy compression of BMP images using compression ratios of around 130:1. In order to achieve an even smaller compressed file size for...
