OK! I'll try to use the second form of the 'push_stripe'. The images to compress aren't greater than 500x500 pixels and, actually, the times I got are ok for...
Hi! I am currently working on a project which has to access and visualize JPEG2000 images provided by a IAS 3.0 Server. I want to use Kakadu as a client...
Hi, I'm making test with jpip and I want to know why, if I set a region in the kdu_window (set_region, set_resolution and make jpip_client.post_window), after...
I just learned about the AMD Firestream GPU card that support double precision... a few highlights: - 320 stream cores - up to 500 GFLOPS single precision -...
Hello, i've tried to download executables on this page : http://www.kakadusoftware.com/Downloads.html but i obtains a archive containing a strange arborescence...
Hello, I would like to control the bits per sample for the 2k and 4k resolution level of ja JPEG2000 file with 6 DWT's, 7 resolutions. When I use the command...
Hello; I do some selective encryption in the codestream and I need to define bits planes in code blocks to encrypt some in the future. The problem that I have...
What does exit status 11 from kdu_compress mean? Is there a listing of the meaning of all possible exit status values for each of the Kakadu programs?...
Does anyone know how to find out the meanings of the exit status values from the Kakadu utilities? In particular, a kdu_compress run has failed and produced an...
Perhaps this is premature, but is anything being done to potentially exploit the new SSE4.1 instructions introduced by Intel? I am certain that GCC probably...
I'm trying to build my own JPIP server and using the kdu-client for communication, I'm adding support for http-tcp connection to but seems have problems...
In my opinion, these kind of studies are useless, since they do not provide any insight into the technology or options provided. Within JPEG2000 Part 1, there...
Hello David, Thank you for your response. Quick question. Is it something that was mentioned in the reference paper which I quoted indicated the color planes...
HI sS, It is not in the paper you quoted and I'm not aware of a specific reference, but the misalignment is the main reason why the luminance plane of Lenna ...
Hello, Does kakadu have rate distortion optimization option similar to RD-optimazation in H.264? Can I use this option using command line option? I want to...
I am vieweing a Quickwave file "(.20d)" extension from a DVR used for surveillance. When the Quickwave application loads a "KAKADU ERR" error message box pops...
Hi, Does anyone used kdu_transcode.exe? I want to change compress parameters from : -rate 1.5,0.001 Clayers=28 Creversible=yes Clevels=8 Corder=PCRL...
Simple, just use "cw.j2c" as the output file and the "kdu_transcode" program will write the transcoded code-stream for you, but will strip the JP2 header...
Your viewing application is, for sure, Kakadu-based. The error appears when the file is corrupted in some way -- yes, it could potentially be legal, but it's...
Kakadu automatically uses RD optimization. J2K is a raw codestream. JP2 is a codestream, wrapped in the JP2 file format which adds some simple information...
Are you using this with "kdu_show" or some other way of driving the client? Perhaps the problem lies with the way the application is using the client. ... ...
Hi Bradford, I really don't know how that exit status could occur. It looks like a call to exit() from somewhere outside of Kakadu, but then you are using...
No actully the problem was in my 8-byte chunk, I was sending the chunk size in an invalid format so the kdu_show was waiting for more data on the TCP channel...
Hi David, I have a 12-bit /sample (36 bits per colour sample) Raw colour file with the following dimensions 1920(L)*1080(H) (HDTV) Can you kindly give me an...
I have a scenario in a JPIP client-server which I can't figure how it should be handled by the JPIP server. Assume that a JPIP client requested an image and...
Dear users, I have lossless compressed a 3D data volume by using the command: kdu_compress -i /tmp/vol.raw\*8@1374310 Mcomponents=8 Msigned=no Mprecision=16...
Hi group. I'm looking for additional information about all datatypes supported by Kakadu. Basically I know it can support 8 and 16 bit images with 1 or more...
Hi, I have a problem when expanding my images, values seem to be shifted with a factor of 2 power precision (12), encoded as signed integer (shift = -2048). ...
Hi Christelle, Internally, kakadu uses signed representations for everything. That means that Y, Cb and Cr are all signed quantities, centred about 0, for...
