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.

31 Jul 2013 B-spline Grid, Image and Point based Registration B-spline registration of two 2D / 3D images or corrsp. points, affine and with smooth b-spline grid. Author: Dirk-Jan Kroon Abdelkrim

Very useful toolbox! Thanks a lot!

29 Jul 2013 Kinect Matlab Microsoft Kinect, OpenNI wrapper, Skeleton, Depth Author: Dirk-Jan Kroon Hussein

I use the mxNiChangeDepthViewPoint(KinectHandles) to align depth and color images, its working fine if I'm online streaming using the Kinect device, but if I used a .oni file I the two images are not aligned, could anyone please advise me how to fix it as I don't have a fulltime access to a Kinect device.
Many Thanks for your kind assistance and support

27 Jul 2013 Viewer3D MIP, Color, Slice and Shaded 3D (shearwarp) Volume Rendering, interactive 3D view/measurement GUI Author: Dirk-Jan Kroon Sebastian

This is very nice.

Some suggestions for future.
1.) Manually set view point. Maybe even output a movie.
2.) Manually set alpha/color. Dragging is very cumbersome.

26 Jul 2013 Read Medical Data 3D GUI to open most Medical file-formats: Dicom, V3D, ISI, NifTI, Analyze and other formats Author: Dirk-Jan Kroon liu

Nice tools.There's a GE Voldicom format, which can be exported from GE vivid ultrasound scanner.Can this format be read?
