OpenCV 2.4.11 users may have noticed that it does not provide pre-built binaries (Libs and DLLs) for VC14 (Visual Studio 2015) Unfortunately it is also the case with Qt 5.5.1 (At least it’s true at the time of writing this article) so if you are going to use either one of them you have to build […]
To get a list of all available Windows Media Codecs in Qt you have no other choice but to use C++ interfaces from Windows Media Format SDK. In this post I am sharing an example source code which allows you to do that in Qt. If you are developing using Qt and MSVC compilers for Windows […]
In this article I’ll explain the process of combining C++ and VBScript codes together. There are many situations in which you find yourself in desperate need of some simple code that can handle what your program wants to do. An example that comes to my mind is using DDE Protocol in Windows. It can be heartbreaking to try and write a […]
I use the following method to make an application remain on top of other windows in Qt: SetWindowPos ( (HWND)winId(), HWND_TOPMOST, window_top_pos, window_left_pos, window_width, window_height, SWP_SHOWWINDOW ); Note that window_top_pos, window_left_pos, window_width and window_height are variables and you can replace them with your own. Please be aware that this is a Win32 API function so […]
This application demonstrates the implementation of multiple Camshift trackers to track multiple objects and regions in a video at the same time. It is written in C++, using Qt and OpenCV. You can find the Executable and Source code at the bottom of this post.
UPDATE: This application is updated. Please read this post for more information. My new application is a tool for for performing Fourier transformation on images. You can then apply masks to the Fourier representation of image and revert back (perform Inverse Fourier Transform) to see how the image gets affected. For more information about Fourier […]
This program allows you to benchmark algorithms in OpenCV related to object detection using key points. It allows you to set all the required parameters using a simple interface and search for an object in a scene and view the results. This program is written in C++ using Qt and it uses OpenCV libraries. Please […]
I wrote this program some time ago to change my Skype status to Online and Away at different hours during the day. I decided I could share the source code because it is a good example on how to connect to a COM library using Qt. Following should be noted about the source code provided […]
