I am installing the TLD application based on the instructions shown on https://github.com/zk00006/OpenTLD/wiki/Installation

Using:

OpenCV 2.4.2

Matlab R2010b x 64bits

Win7 x 64

VS2010 Professional

Everything works fine until I executed this step "6) In Matlab, run compile.m"

I have searched through many websites but to no avail. Hopefully, someone can enlighten me on this problem. All solutions are greatly appreciated.

If you have read the instructions well, and followed them, then you must have created the .mex binary output files. That is compiling the mex files that contain opencv codes. You are getting the errors as you have not been able to compile them properly. Check the folders for mex32 files.

Here are the step to accomplish a complete compilation and a successful run, hope this works for you

1 - Install OpenCV 2.2, not beyond 2.2. This get crazy if you try to do so. And install it to C:/OpenC2.2, maker sure you do not use any spaces. Spaces makes path search in Matlab go coo coo. Actually spaces are broken up in Matlab.

2 - If you have a x64 system, with 64Bit Matlab (2011) and 64Bit C++ compilers, you will need select via 'mex' compiler options a 32 bit compiler. I used MSVC C++ 9.0 32 bit compiler.

3 - Once you have selected the compiler, do the compilation. You must have a successful compilation. Try using the debug flags for compiler and once compilation completes you will get an output. If any errors occur, try fixing them.

4- What this means is that donot change any paths that have been set in OpenTLD to find OpenCV2.2 - This is the most tricky part. You can install openTLD anywhere. Just make sure that you have selected 32bit C++ compilers. NOT 64bit.

Once the above is done. You should be able to do a run. OpenTLD is cool after the first run!
