Particle Filter Color Tracker

Tracking an object in a video with a Color Particle Filter

Description

A simple example demonstrating how to track an object with particle filter. Likelihood function is based on Bhattacharya distance of color histograms and gradient distributions

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

Run the two demo files test_pf_colortracker and test_pf_colortracker2

IMPORTANT. Be sure than you "mex -setup" had been done before compiling sources

• MATLAB release: MATLAB 7.5 (R2007b)
• Other requirements: A C Compiler such MSVC/Intel CPP/GCC

[Tom Pinkiewicz]

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.

[Hong 4]

I found a paper relates to this subject:
K Nummiaro, E Koller-Meier, L Van Gool, An adaptive color-based particle filter, Image and Vision Computing, 2003 - Elsevier

[Duy Nguyen]

Thank for your sharing, Sebastien. I want to get more detail about this issue, can you give me reference for this ones.

[Duy Nguyen]

 

[tarun goel]

Hi sir, it is indeed a nice work and thanx for sharing it. Could you please tell some refeence material where the meaning of variables can be understood as their names are of little help. Iwud be highly thankful.

[Kevin Murphy]

 

[tejaswini kar]

sir can i get the reference material of the codes for my work.actually i am unable to understand it.is it possible that either the whole program can be written in matlab or written in c.why u have used both c an matlab. what is the advantage.

[Sebastien Paris]

to kar: as we say in french "pour avoir le beurre et l'argent du beurre".... in other words, the easiness of matlab and the speed of C.

[Jake]

Thank you for sharing, I just wondering did you pick a importance density in this program?

[oj]

Dear sebastien I am unable to get the program in running condition... Even though I have replaced mmreader for aviread... still cudnt fix problem... help anyone..

[Sebastien Paris]

Jake: here IS used here is independant of the current measure so ... q(x_k|x_{k-1},z_k) = p(x_k|x_{k-1}) here ...

[Sebastien Paris]

oj: If I have time, I'll update with mmreader instead of the old (and depreciated) aviread

[Selva]

Thanks for sharing dude..

[Chi Chin]

I get the following error on Windows 7(64-bit) and MATLAB R2009b. 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);

anyone can help me?

[Sebastien Paris]

Chi,

Maybe install a video codec pack such K-lite mega codec in your system. Regards,

[Chi Chin]

Hi Sebastien,

Thanks for your prompt reply. I had installed the K-lite mega codec in my system but it still give me the same error :<

[Sathiyaraj Manoharan]

Hi Sebastien:
I am new to this can you explain how to execute.I m getting error like C file is not found.I think that because of the mex compiler. how to install that with brief.Is it necessary to install VC++ 2008 express.Can I run it in Matlab2011.

[Sathiyaraj Manoharan]

Can anyone explain me how to install the C compiler and compile the C files in MATLAB..

[zhao]

My matlab7.0 can not find function 'mmreader'. If aviread is used,can tell me where should be replace in the files.
thanks

[zhao]

 

[Sebastien Paris]

Zhao,

Instead of badly rating, please have the nominal configuration requiered.

[zhao]

Hi Sebastien,i modified the files,and Create more problems. If i want to run the files in matlab7.0, can you sent the right files to me. My email:[e-mail],thanks a lots.
