Hiding data in Images

Here is a still from my favourite movie

The Martian

Now, what if I told you that I have hidden a big message inside this image. Would you be able to find out what it is?

OpenCVKinect 2.0 - Acquiring Kinect depth stream in OpenCV

It has been almost two years since I first wrote the code for OpenCVKinect. It has been really good to know that it has been used by a number of other students/developers at GitHub for collecting and analysing Kinect depth streams in OpenCV. I have had some feedback about a possible bug and some students have asked how they can visualize the depth maps in a better way. So today, after a long time, I am releasing the first official update to this project.

Compiling OpenCV-3.0 with Matlab Support

A big uppercase HELLO to everyone!  I am back and after a long time (yet again) I am going to write a tutorial. The thing I am able to achieve here is awesome for us computer vision researchers. Yes! you heard it correct, exciting stuff.

I have been using OpenCV for quite sometime now. As good as it is for real-time computer vision applications, it can also be time consuming when it comes to exploring and implementing new research designs. Matlab on the other hand has always been flexible and a quick work around to achieve my research goals. The only problem, though, with matlab is that it is not real-time or even worse is that if you plan to implement code in OpenCV for real-time application, you would have to write the algorithms all over again as the usage of Matlab toolboxes is different than using the same methods in OpenCV.

Now comes the fun part, what if you can access OpenCV function calls within Matlab code? What if you can have easily transferable code from Matlab to C++?  This is all possible now with the OpenCV 3.0 Dev including matlab mex wrappers, which really is a good big step in the right direction. So lets start compiling the code.

OpenCV-2.4.X Binaries pre-compiled with Visual C++ support

Update (07/05/2013):
Below are the different versions of OpenCV binaries I compiled from source on Windows 7 using Visual C++ 2010

1. OpenCV-2.4.3VC
2. OpenCV-2.4.5VC

You can use either one of the above binaries and set up as follows:
 

To set these binaries up, extract the contents of this folder. Edit the SYSTEM ENVIRONMENT VARIABLES to add the path to \bin folder similar to what has been done in my previous post

Please post any problems in comments below.
