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

31 May 2012 Biggest Connected Component This program is an example for image processing in order to obtain the biggest connected component Author: Gholamreza (Shahab) Anbarjafari

Can be done in 3 lines, without for loops with bwlabel, hist (or accumarray) and max
24 Apr 2012 Shape Context Based Corresponding Point Models Shape Context based nonrigid registration of 2D/3D objects, to build Active Shape Models Author: Dirk-Jan Kroon

*Birgit
Knnsearch is part of the "Statistics Toolbox" of Matlab. Maybe you can find a similar but free implementation on the File Exchange
19 Dec 2011 Polygon2Voxel Convert a triangulated mesh into a voxel volume Author: Dirk-Jan Kroon

*leo,
Only integer volume sizes are supported
24 Oct 2011 Kinect Microsoft SDK Video, Audio, Depth Stream and Skeleton tracking Author: Dirk-Jan Kroon

*Tim

The x,y coordinates are aligned with the depth image, which is twice as small as the video-stream. Thus this code : x=(Pos(1:20,5)-0.5)*2; transfers the coordinates from depth to photo image.
But this is only true if the depth image and photo image are aligned, and I don't know if that is always true.

29 Apr 2013 Read Medical Data 3D GUI to open most Medical file-formats: Dicom, V3D, ISI, NifTI, Analyze and other formats Author: Dirk-Jan Kroon Law, Max W.K.

I like this piece of tool. However, is it possible to take out the GUI? I have like 500 files need to be loaded and processed, and written the processed data back to the drive.

It takes about 30mins to finish one volume. I want everything to be automated so that my computer can work over weekend.

Hi,
Nice code. Could you tell me how I can modify it to detect vehicles?
