QImage blur, sharpen etc.?
-
Is there any way to blur, sharpen, edge detect, desaturate, or otherwise perform complex operations on a QImage in a way that would draw upon the native hardware to accelerate it?
I notice there is nothing like QImage::gaussianBlur(...).

Hi,
Looks like you would be interested by OpenCV GPU's offering.
Work with it to do the analyses/changes you want and create the QImage once you're done.
Note that with a bit more details about what you want to implement it will be easier to determine whether there's something suitable in Qt directly for you.

@SGaist Oh darn, I was hoping Qt has this built-in e.g. that it would use OpenCV if available when Qt itself was compiled.
As it happens my Linux distro (32-bit Raspbian at the moment) has a broken OpenCV with missing dependencies. -
It was the other way around, OpenCV used Qt as one of the backend for its highgui module.
