How to use ippiDecodeCodeBlock_JPEG2K?

[e6milu]

Hello,

I will decode some jpeg 2000 images and will use the functions provided by IPP.

I'm a litte bit confused about the the parameters to this function - first of the data source: is that the code stream of the jp2k-file or is it only a part of it?

What is the number of passes?

Anyone that has used this function?

Thanks,
Michael

Hi Michael,

Intel Integrated Performance Primitives is set of low-level optimized functions in wide range of functionalities. In other words, these functions are building blocks for developers, who can combine them to implement different applications (including codecs). To simplify them their taskwe demonstrate how to use IPP functions to build somethings useful. Please take a look on IPP Samples page. There you can find many samples in different areas including JPEG2000 codec. The only thing you need to do - is to download IPP anddesired samples and to build executable. Each IPP sample comes with readme.htm file where we briefly described implemented functionality, existing limitations (if any), software and hardware requirements and how to build this sample. So, go ahead and enjoy with IPP :)

We also will be glad to get from you any feedback about functionality, performance, what is missed and so on. This information can help us in further improvement of IPP and samples.

Thanks,
Vladimir
