01 Apr 2014 Web Server HTTP Matlab Web Server, allows m-files to be executed in a browser Author: Dirk-Jan Kroon

*CdC
This software is only a small demo I wrote for fun, and never tested with more than one user.

Probably it is also not really suitable for multiple users, because Matlab is in basis single threaded.

A solution is using a real HTTP server like Apache, in combination with PHP (see easyphp.org).
Then compile your matlab-code to a executable and simply parse the user inputs/outputs to that executable through PHP.

21 Feb 2014 Patch Software Render Patch Software Render with Phong-shading, shadows and textures Author: Dirk-Jan Kroon

Note, in this version is the following bug
Line 34 in renderpatch_shading.cpp:
if(L[3]==0)
Is a bug, must be:
if(LP[3]==0)

Thank you, there was a bug which I solved by removing abs from the eigenvalues. This version will probably be online in one or two days.

11 Oct 2012 Web Server HTTP Matlab Web Server, allows m-files to be executed in a browser Author: Dirk-Jan Kroon

*Filipe S.
A Matlab GUI/Figure is user-interface thus client-side, this is a webserver thus server-side.
The only way to do client-side things like showing a GUI, is manually coding the GUI in javascript, html and css

24 Jul 2014 Active Shape Model (ASM) and Active Appearance Model (AAM) Cootes 2D/3D Active Shape & Appearance Model for automatic image object segmentation and recognition Author: Dirk-Jan Kroon Hongyu, Wang

Thank you very much for the sharing.I hanve a question about how to create the simulation data in the 3D ASM algorithm(eg:V 400*400*352 logical).

Thanks again.

17 Jul 2014 Kinect Matlab Microsoft Kinect, OpenNI wrapper, Skeleton, Depth Author: Dirk-Jan Kroon aziz, azim

Hello,
I successfully compiled the compile_cpp_file but when i run the Example.m, i got this error :-

Attempt to execute SCRIPT mxNiCreateContext as a function:
C:\Users\zg834397\Documents\MATLAB\kinect_matlab\OpenNI1\Mex\mxNiCreateContext.m

Error in Example (line 6)
KinectHandles = mxNiCreateContext(SAMPLE_XML_PATH,filename);

Could someone help me?

Thank you

15 Jul 2014 Senz3D Acquisition interface Creative Senz3D, Intel Interactive Gesture Camera (Time of Flight), Acquisition interface. Author: Dirk-Jan Kroon Wu

I received the same compile errors:

pxcColorImage.cpp(110) : error C2660: 'PXCProjection::MapColorCoordinatesToDepth' : function does not take 3 arguments

PS: Senz3D is not a TOF but a structured light camera.
