Image Data Conversion between Intel IPP and OpenCV

Hello, I'm using Intel IPP in my project. Yet Intel IPP lacks an image display function. I'd like to use OpenCV to display images.

Is there a built in or an easy way to convert image data from Intel IPP form into OpenCV form? Does anyone have a sample code?

Thank You.

It is easy to convert any kind of image to OpenCV format as long as you have pointer to buffer where the image is stored. For example:

Mat imageWrap(Size(width,height), CV_8UC3, buffer, step);

CV_8UC3 - defines that the image should be of unsigned chars (8U) and 3-channel (C3).

step - is step/stride/pitch (or whatever you name it) between subsequent rows in buffer.

This operation does not perform any coping operations, so any changes that will be applied to imageWrap are actaully applied to original buffer.

Any specifics related to Intel MKL? Thanks.

Nothing specific for Intel MKL as far as I know
