Load a jpeg efficiently using IPP

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

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.
