In this post I’m sharing a couple of very simple tricks to perform an efficient Rotate or Flip (Mirror) operation on OpenCV Mat images.
This is a post that many people have requested recently. I’m going to describe how you can use OpenCV in Unity. Of course we’ll be using official OpenCV libraries and not any assets or existing plugins. For those of you who aren’t familiar with the subject, Unity is a very popular game engine which allows […]
In this post I’m sharing the pre-built libraries and binaries for OpenCV that I use to build Qt/QML and OpenCV powered apps for Android (armeabi-v7a) phones. An example of such application is Quick-Camera-CV which I shared its source codes in a previous post.
I have avoided using QML for long time and always wrote even the most simple applications using Qt Widgets and C++ code but the release of Qt’s Quick Controls 2 and Material Style just made it very irresistible and I had to go for it. Well it didn’t take too long to get a hold of things […]
This one is taken from one of my favourite books (OpenGL 4.0 Shading Language Cookbook) and the relevant chapter’s title for this tutorial in the book is called “Implementing diffuse, per-vertex shading with a single point light source”. Of course it’s modified to use OpenGL ES in Qt which is more cross-platform and creates less […]

First of all let’s briefly go through what’s an OBJ File. Here’s a very brief description from Wikipedia: “OBJ (or .OBJ) is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package. The file format is open and has been adopted by other 3D graphics application vendors.” Anyway, I’ll […]
If you’re a regular Qt user (like me) and have tried writing Android applications with Qt then you must have come across situations where you’ve needed some very simple capabilities of Android API but it wasn’t present in the Qt library. Displaying a Toast message in Qt for Android is one of those situations. In […]
Bu iki beyti yine yazmalıyımdır meleğim Nefesi sözlere aktarmalıyımdır meleğim Bu işin kürdü de yok, türkü de yok Arap, acem, hepsi yalandır meleğim Bu yalanlarla bizi hep ayırırlar Seni benden, beni senden meleğim Bizi düşman kılıp asude olurlar Ama her şey, sonu vardır meleğim Bu dövüşler, bu savaşlar, bu ölümler Bir sabah uyandığında bitecektir meleğim […]
You can use Cascade Trainer GUI to easily train and test your cascade classifiers. It has a very simple user interface which helps with everything related to training cascade classifier that are usable with OpenCV. Starting from preparing the positive and negative image data set, its cropper tool will help you with quickly preparing your training data set. […]
