Image sharpen filter
Is there any build in class for applying sharpen effect on a QImage, or any library I can use to apply such filter?
@son4ety Hi! AFAIK there are no image filters in Qt. If this is for scientific stuff etc then have a look at OpenCV and Matlab.
Hi, I know that there are classes for applying a blur effect on an image - QGraphicsBlurEffect Class ( http://doc.qt.io/qt-4.8/qgraphicsblureffect.html ) and I am wandering if there is something similar for sharpen effect or is there a way to use the Blur class for making sharpened image.
You could take your image, blur it and subtract from the original, this will sharpen it. However this is the most rudimentary way to do it and there are a lot of different ways to have an image sharpened in a more sophisticated manner.
