Load a jpeg efficiently using IPP

darko-radiceski — Wed, 10 Mar 2010 03:52:57 GMT

Hi all,

I have downloaded IPP but cant see to find a good example on how i can use IPP primitives on how i can load a Jpeg file form disk so i can compare that with the existing load method.

I would like to see if IPP load will be faster then what i have now.

Has anyone encountered an example on how to efficiently load jpeg image form disk?

Any advice would be appreciated.

Cheers

Dan

Hi Dan,

I would recommend you to take a look at IPP Sample package which is separate download. When you unzip the archive please look at image-codecs\uic folder for Intel Unified Image Codec API sample. Note, we also provide sample of standard libjpeg library boosted with IPP (you will find it under image-codecs\ijg folder).

Regards,
Vladimir

Here is link to an article about IPP sample code description and download information of different type of sample code.

Hi Dan,

It is best to build the sampleipp-samples\image-codecs\jpegview.

Run it in debuuger and set break point in file jpeg.cpp function:

ReadImageJPEG

You can see how the jpeg file is loaded.
