Particle Filter Color Tracker

Tracking an object in a video with a Color Particle Filter

Description

A simple example showing how to track an object with particle filter. Likelihood is based on Bhattacharya distance of color histogram.

Please run mexme_pf_color_tracker to recompile mex-files on your own plateform.

• MATLAB release: MATLAB 7.5 (R2007b)
• Other requirements: A C Compiler

The C files compiled okay but I get an error that function part_moment is undefined. Are you missing a file with this function?

[Sebastien PARIS]

You are right. I have just update with the missing file. Thx you....

[Tom Pinkiewicz]

It works now and it looks excellent. Well done!

How to recompile each mex files?

[loi yii tien]

How to recompile each mex files? and i got error...

??? Invalid MEX-file 'C:\Program Files\MATLAB71\work\pf_colortracker\rgb2hsv_mex.dll': The specified procedure could not be found.

.

Error in ==> test_pf_colortracker at 202
im = rgb2hsv_mex(Z);

hope to hear u soon!

[loi yii tien]

Actually i am doing the object tracking in video using neural network. Can you send me an example of it if you can do it. Thanks!

[Sébastien Paris]

Please recompile with the following command :

mex -output rgb2hsv_mex.dll rgb2hsv_mex.c

[ophelka flowerfairy]

to recompile simply use
mex filename.c

[li jackey]

how to recompile mex files?when the file is compiled in VC platform,the problem is always that mex.h can't be found,how to deal with it ,please tell me quickly,thank you

[prabhakar raj]

i want the code for tracking faces in an image sequence using particle filter,can u help me in this

[nauha jam]

Thanks for program.I would ask about the LAB model of color image in matlab

[min hu]

thanks for program.it is very good.

[XU FENGLIANG]

thanks for you sharing

[David Norville]

I'm having some trouble recompiling with the part_moment.c file. It says there is an undefinded reference to '_max'. Can you help me please.

[David Norville]

Got it to work. Thanks

[Ravi Prakash]

For all those laymen like me who couldn't get it to work in the first attempt. Type inside the MATLAB command window

> mex ellipse.c
> mex rgb2hsv_mex.c
> mex pdfcolor_ellipserand.c

In both files part_moment.c and particle_resampling.c at the top add the line
#define max(a,b) ( (a) >= (b) ? (a) : (b) )

Then
> mex part_moment.c
> mex particle_resampling.c

Finally to run
> test_pf_colortracker

Thanks Sebastien. FIGHT ON!!

[Sebastien Paris]

Ok, I'll update with a mexmefirt.m file for mexfilers beginners

Thx all for comments/ratings

[Tedo Biresaw]

Wow! what really a nice work.
I get it work.

[M]

I get the following error on Windows Vista (64-bit) and MATLAB R2008b. Can anyone assist?

??? Error using ==> aviread at 76
Unable to locate decompressor to decompress video stream

Error in ==> test_pf_colortracker at 196
mov = aviread(video , offset_frame + 1);
 

PS: I tried installing CINEPAK, but it didnt work! :(

[Sebastien Paris]

Ok, you can replace the aviread function with the new one 'mmreader' to read avi files.

[yasong guo]

i have solve it now!thank you for your codes .wonderful!thank you!!!

[Fang-I Chu]

can i ask if i want to track a moving object under grayscale, what is it different from color tracking?

 

[Janayna]

did you use any paper to implement the particle filter?
Thank you

[Yong Zhao]

thanks for you sharing, I'll study and discuss with all of you.

I found a paper relates to this subject:
