Meleğim

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

Geriye toz bile kalmaz göreceksin
İzleyen sen olacaksın meleğim

Ne olursak olalım, bu can emanet
Vereni bizleri hep izleyecektir meleğim

Best Way to Train and Test Haar or LBP Classifiers

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. Just make sure you have enough videos of the object you want to train a classifier for, and detect. It also allows avoiding all the complexities of setting parameters for the training. Of course if you want a very high quality classifier, then you’d have to touch a few parameters here and there but for the most part, it’s select and Go.

You can use the Train tab to train a classifier, and then use the Test tab to test it on a video or image. And switch between them as long as you’re not satisfied with your classifier’s performance.

You can always download the latest version of Cascade Trainer GUI from its official website, or by clicking here:

Picture Stamper version 2.8.0 adds opacity support for logo and watermark

Today I released a new version of Picture Stamper after quite a while. This version addresses a few minor issues in the user interface and also as of this version (v2.8.0) you can also set an opacity level for Logo and/or Watermark text that you add to the images. Pretty much everything else is the same, but you can find out for yourself if you head to official Picture Stamper page.

How to Get Current App Version in Qt

I have tried numerous methods to get an application’s own version number and believe me this is the best way to get it. First of all if we consider the fact that setting a Qt application version is done in PRO file (qmake) using the following simple command:

VERSION = 1.2.3.4

Then getting this same value should be the easiest possible method.

Just add the following line to your PRO file after defining version as seen above and you can use the same version string wherever you like in the code:

DEFINES += APP_VERSION=\\\"$$VERSION\\\"

APP_VERSION will contain the string “1.2.3.4” and can be used in the C++ code.

Qt Creator Issue on Mac OS X Fix (xcodebuild issue with Xcode 8.0)

When using Qt creator following error starts rising up when Xcode gets updated to version 8.0 and it’s because of a change that is not yet applied in Qt settings. In my case it happened with Qt 5.7 and Xcode 8.0 on Mac OS X El Capitan but I think it’s safe to assume similar issues will start rising up with other kits too. Here is how I fixed it.

Qt Application Fonts Missing or Invisible in Linux (Fixed)

By default Qt does not copy fonts along with your application when you deploy them under Linux. I recently faced this issue and none of the texts or labels on my Qt windows showed anything on them. All labels and text were blank and the forms looked completely empty.
