Hello Ariya,

Thank you for visiting my blog. I’ve seen the function on the documentation already, but it was worth trying to do it my own in order that I can learn new things and for example to see how mirrored() function works just for education purposes, every time I learn new things and make something of my own I post it here but it doesn’t mean that I will use my own implementations on production, but thanks and credits goes to you guys for the great framework!

LOL, when I finish my exams I will have more time to do that, but exploring Qt and seeing it as very powerful C++ framework I want to experiment with it in various fields just to know the framework better. As for fast image manipulation I don’t know and I don’t have time now to compare them, but I will send you an email with Windows build of that application and you can test it, because application allows you to select any image.

I’ve been working recently with image manipulation (in C#) and my first approach was similar to the one you use here. I was trying to apply some computer vision algorithms, and this approach (pixel by pixel) is extremely slow.

What helped me a lot was the OpenCV (Open Computer Vision) C++ library developed by Intel, which is optimized for work with their processors.

http://sourceforge.net/projects/opencvlibrary/

All the image processing is done in lower level, thus you will result with great performance. It also supports bit more than 500 advanced algorithms starting from basic image processing to very advanced machine learning tasks.

Knowing you, I believe soon there will be a new blog post about OpenCV

Well it’s not that advanced! It’s very simple if you are in the field. I used your photo because it has a special meaning for me.

Well done
