Hi Mourad, For efficiency reasons, there is not a separate phase which adds the mid-point offset. Instead, the block decoder introduces the offset by...
Hi Mourad, First, you need to appreciate that this function executes one of 4 different conversions, depending on whether the data precision is 16 or 32 bits ...
HI Jukka, Thanks for pointing this out again. At first, I could not see what the problem was, since my Windows build successfully compressed and rendered your...
The gdal_merge.py python utility does create by default GeoTIF files that are interleaved by band. Unfortunately for everyone, these GeoTIF files, aside from...
I am pleased to learn there is a simple fix for a bug in image_in.cpp, and with this fix kdu_compress is better able to process TIF images interleaved by band....
Hi David, What do u mean by OR in the next two less-significant bits? Do u mean by that taking the next two less-significant bits. Perform an OR with these two...
Hi, I have some query regarding jpeg2000 codec in yahoo live video chat. As we all know that yahoo video chat uses jpeg2000. So can anybody tell the format in...
Hi, I would like to know if the YCbCr compulsorily an Irreversible Color transform or like can an reversible color transform, which uses implmentable integer...
Good evening friends, The difference b/w the two famous libraries available for jp2 ie kakadu and geoJasper are speed, ROI implementation, which I came to know...
Amit, JasPer does not seem to be improving or evolving. The current version was finished a few years ago and no bug fixes even seem to be forthcoming. ...
While Jasper did sit for a while it was recently updated to version 1.9 (as of 12/7/2006). See http://www.ece.uvic.ca/%7Emdadams/jasper/ and because of it's...
Hi David, Okay, I've looked at this but I still need some advice (i.e., help). My requirements are Layer 0: 0.03125 bpppb, Layer 1: 0.0625 bpppb, Layer 2:...
An updated version of Jasper was released by Professor Adams on 8 Dec 2006. JasPer and GeoJasPer are both released with an open source license. I use both...
Hello, I would like to create tile parts for each color component. Whatever I do I just get 1 Tile Part. The next thing is that I would like to be able to...
I'm trying to compress six uint8 channels using Part 2 multicomponent wavelet transforms, but I'm not having much luck. Eventually I just want to use...
You can use "ORGtparts=R|C" (probably need to quote it in your shell) and "Corder=CPRL" to get an image with 3 tile-parts (one for each colour component) for...
Hi John, Multiply bpppb by the number of bands and the number of pixels in the image (spatially) to get the total number of bits, over the image. Divide this...
HI Sean, The reason for the error message is that "Mstage_collections:I25={5,5}" describes a transform from 5 components to 5 components, whereas you have 6...
This aspect of the library is still too perplexing for me so I went ahead and implemented what I think is a Haar decomposition as a single-pass SSE2 integer...
In the demo application, there is a rectangular area within the image window that represents the region of interest and hence this area is where the detailed...
I am pleased to report that Kakadu version 5.2.6 compiles successfully under Mac OS X 10.4.8, on Apple PowerPC G5, and Apple Intel Macintosh computers....
I wrote principal component analysis code and have an eigenvector basis for the KL Transform for each image. I read the reversible integer mapping papers...
I am developing Joint Source-Channel Coding simulations for Telemedicine networks, by QoS and distortion metric tests. I want to know if Kadaku can make these...
Also, I am comparing between the filters used for ECBOT and for Wedgelets and Contourlets, again, using Qos and HVS metrics for distortion by compression test....
I'm trying to extract a scaled portion of a jp2 image using Kdu_region_compositor. I'm setting the Access_size(), but it is getting changed by the Process...
Sorry, that piece of code doesn't show the problem I'm having. debug_dims is coming back equal to view_dims, which is correct. The problem is that the change...
Here's an example: An image with the pixel dimensions x = 6283, y = 7035 scaled down to scale = 0.02 I get x = 125.66 and y = 140.7 kdu_region_compositor...
is there any SDK available to check the utility of Kakadu according to my needs?? Or any other way to solve the purpose. Thanks in anticipation Amit Bhatia...
