Image Transformer (Fourier Transform App for Android)

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 Transform you can check out this link.

It is built using OpenCV and Qt and it is programmed completely in C++. I hope it would be useful for Image Processing and Machine Vision enthusiasts, researchers and students. It also contains some useful tips and tricks for programming Android applications using Qt and OpenCV such as:

  • How to open Android image gallery in Qt (Default interface)
  • How to capture images using default Android camera interface
  • How to crop images displayed on a QLabel
  • etc.




Source code (any part of it actually 🙂 ) is available upon request. Please send your requests using the Contact Me page.

Please consider supporting this application by giving a decent rating in Google Play.

For an example of Fourier transform using OpenCV please check out this link.

OpenCV Feature Points Comparison Program (Executable + Source Code)

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 note that this program should only be used for educational purposes. In my case I was using it for research purposes and as a tool for deciding which algorithm I should use in my programs.

CATOX 2000

CATOX 2000 is a fully automatic metal sheet cutting system built by Ahmadi Industrial Group during 2000’s. It is able to get AutoCAD drawings as an input and cut the drawing from a metal sheet (iron, steel and any other metal type depending on the cutter section of the machine which can be Oxygen-Propane, Plasma or Laser) CATOX 2000 is widely used in heavy industries.

Opticount

Opticount is a highly accurate sheet-counting machine used mostly in packaging industry. This machine uses sophisticated electronic components (sensors and cameras) along with recently developed methods and algorithms in the field of artificial intelligence, image processing and machine vision. Opticount is currently being manufactured and sold by Paxan (http://www.paxan.com.tr)
