Hi Mr. Taubman & others, Can anyone tell me how to separate ROI data from the rest of the codestream? I have compressed an image by the following command ...
Hi Alam, There is not generally a hard distinction between the coded bytes which represent the ROI and those which don't. You could decode each code-block and...
Hello Folks, Following Johnny's question, I want to know if we can directly use a YUV image as an input with a fxied sampling ratio for three components (such...
Hi, Some months back Dr. Taubman suggested that support for multi- threading was likely to be added to the library - is there a more accurate date - is it...
HI Steve, I decided to add a whole slew of Part 2 features (including arbitrary wavelet kernels, arbitrary transform structures and sub-sampling factors, and...
Hi everybody, I would like to know if it is possible to specify the bitrate of a single resolution level in one special layer while using an object of ...
Hi, I would like to have access to the wavelets coefficients before quantization for the whole image (subband by subband). I try to open the code-blocks after...
... I am also looking for a feature like this, to specify a maximum number of resolutions that data is taken from for a certain quality layer. So instead of...
Dear Prof. Marcellin I’ve received my MS degree from Sharif University of Technology, in communication systems, in September 2004. My field is Image and...
Hi I just have a small suggestion to kakadu code. The code as it is, it is a nightmare to port it to .net. The Microsoft's framework 1.1 uses the word new for...
The current version of Kakadu is 4.5.2 You can download Kakadu executables from http://www.kakadusoftware.com/downloads.html kdu_compress -version This is...
Hi Manuel, This comes as a big surprise to me, since I use .net extensively for Kakadu development and include the workspace files. Are you saying that the...
Hi David, I was wrong about one thing, since in the core components you do not allocate memory in *.h. Allocations are in kdu_show, which i used to help me ...
Dear experts, I was wondering if there are such techniques implemented in the current or future release of Kakadu (I am not very familiar with the software). I...
... There may be a semantic problem here as well. Just like the old "ActiveX" terminology, Microsoft has plastered the ".NET" moniker on a lot of unrelated...
Hi Anyu, If you don't have any other requirements, of course you can just pack the data any way you like. The real issue is what else you want to achieve ...
Dear Dr. Taubman and all, I am trying to estimate distortion from RD slopes. However there is a huge difference between the estimate and real distortion as...
Hi all experts, After working a few weeks on Jpeg2000, I am wondering "why use quality layers in a viewing program using JPIP like kdu_show ?" I'm asking...
Dear Mr. Taubman, I was trying to separate ROI blocks exclusively from the Codestream in version 2.2. But I became confused about the properties of a block...
Hi Mehdi, Your question is confusing. Do you mean, why use quality layers when compressing the image? In this case, the answer is easy. Just try serving an...
Hi all, Is it true that kakadu has the L parameter of the TLM segment always set to 01100000 in binary? ( Since in kd_tlm_generator class, it defines a struct...
Folks, I have been given the task of designing a JPIP proxy server. Our system is intended to support one or more remote JPIP servers and several clients. The...
HI Simon, I have a MS student who has built an experimental server along these lines -- I have in mind at some point in the future to build a nice JPIP proxy...
Dr Taubman, I am currently writing an application with the aim to be able to display a MJ2 file across a JPIP connection. I was just wondering when you think...
Hello, is there somewhere a clear example of the usage of kdu_region_compositor? I mean, it is used in kdu_show, but it is a little bit tricky to understand at...
Sounds like something I really have to do. Very little is actually required to make "kdu_region_compressor" do everything you want, but I should write a...
Sec:u dynamic cache support for mj2_sourceHI Cameron, This is a next step (sort of), but I still have not released the multi-component implementation (very...
