Hello Sir,

Can you please explain me for the usage of the .mw* file in MATLAB. Thanks

Add fdtool dir in your path and run "mexme_fdt.m" to compile *.c files

09 Nov 2009 Face Detection Toolbox Faces detection using Local Binary Patterns and Haar features Author: Sebastien Paris Nessrine

i 'm not soo good in matlab implementation but i would like to test this code. can any one help me specialy i have no idea to use .c file with matlab for me this is the first matter.
thank an advance

Thanks you Soeren for these indications and comments.
Please if you have better models than those already included, I'll include them in a future release.

to build vcagp2.cpp (used in demo_detector_haar as camera acquisition provider) there are some other tricks
1. create a dummy dxtrans.h which seems to be missing in the SDK:
c:\Program Files\Microsoft SDKs\Windows\v6.0A\Include\dxtrans.h
#define __IDxtCompositor_INTERFACE_DEFINED__
#define __IDxtAlphaSetter_INTERFACE_DEFINED__
#define __IDxtJpeg_INTERFACE_DEFINED__
#define __IDxtKey_INTERFACE_DEFINED__

see: sample from http://www.riseoftheants.com/mmx/faq.htm#mjpegsample

2. some changes in code to be able to compile with VC08 and the current SDK in Win64:

82d81
<
629,630c628
< // pbmi->hInst = (HINSTANCE)GetWindowLong(GetFocus(),GWL_HINSTANCE);
< pbmi->hInst = (HINSTANCE)GetWindowLongPtr(GetFocus(), GWLP_HINSTANCE);
---
> pbmi->hInst = (HINSTANCE)GetWindowLong(GetFocus(),GWL_HINSTANCE);
958c956
< wc.lpfnWndProc =(WNDPROC) WndProc;
---
> wc.lpfnWndProc = WndProc;

in addition to my prior post:
to build vcapg2.cpp you need to have a current Microsoft DirectX SDK installed...

excellent work!

to use it with matlab R2009b x64 on win7pro64 I had to change mexme_fdt.m a little bit:

44c44,46
< lib = ['"' , fullfile(matlabroot , sprintf('extern\\lib\\%s\\microsoft\\libmwblas.lib',computer('arch'))) , '"'];

Very good function used on my project. Thanks.

You are right, I'll upload a version with argument checking. Thanks

02 Oct 2009 inpoly mex file Find points inside or on the border of a polygon Author: Sebastien Paris Kua, John

Thanks! This has been very useful on a number of projects!

One problem - the function does not handle an empty input array of [2 x 0] and crashes MATLAB. Adding a check of the input dimensionality with a warning if the input is empty and perhaps returning an empty array would be nice.

Hello Mr. Sebastien Paris,

Thank you for your help regarding to my last question. Now I need your help to study path loss characteristic in 2D database. Here I got a 2D database. When I tried to load the database base using 'imread' command and then load the file in your multiwall model, MATLAB unable to load the file. So, if you have any idea regarding to this post, please help me Sir.

Thank You,

Sincerely Yours,

Sharim

Hello Mr. Sebatien Paris,

I'm interested with the 2D Multiwall Model. Here Im just curious about the reference value and power factor decay that you used. May I know which propagation model that you referred for both of the values.

Thank You,

sincerely Yours,

Sharim

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

Ok, the getpts function is from the image processing toolbox. There are plenty of similar functions in the FEX.

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

Did you run "mexme_first" before ?

Which compiler do you use ?

what's wrong with :

mex poisrnd.c matrixjpl.c randomlib.c

?

what is "ignpoi" mean? How to define it?

Yes,

You can tweak this mex-file as you want ;)

05 May 2009 WiFi RSSI with NDIS protocole List Wifi devices and retrieve RSSI values of the signal Author: Sebastien Paris Weber, Mark

Hello,

thank you for your help. I compiled it with a new Matlab and it is working fine now. But one problem again: How can I see which AP (Mac-Address) has which RSSI values? At the moment I only get RSSI values as I specified but I do not knwo from which AP? Is it possible to get something like this:
MAC1: RSSI1, RSSI2, RSSI3,...
MAC2: RSSI1, RSSI2, RSSI3,...

Thank you for you help in advance again.
BR Mark

05 May 2009 WiFi RSSI with NDIS protocole List Wifi devices and retrieve RSSI values of the signal Author: Sebastien Paris Paris, Sebastien

Well, the included compiled mex-file is not working with your system. You have to recompile it for your system sorry. I don't have the last VS2008 in hand, but I think the compiler is only recognize with the last R2009a. So either you install a prior version of VS, or the newer version of matlab ...

Regards

04 May 2009 WiFi RSSI with NDIS protocole List Wifi devices and retrieve RSSI values of the signal Author: Sebastien Paris Weber, Mark

Hello Mr. Paris,

very nice idea your WifiRSSI. But i have a problem using it. Here my setup: Matlab R2007b and WindowsXP SP3. The driver can be started successfully:
>> !net start ndisprot
The EP_NSWD NDIS Protocol Driver service was started successfully.

But if I use your examples like
y = wifiRSSI([] , 100 , 10);

I get errors:
??? Invalid MEX-file 'C:\Documents and Settings\Mark Weber\My
Documents\MATLAB\WIPoS\wifiRSSI.dll': The
specified module could not be found.

Recompiling is very difficult because VS 2008 is installed on my system. Maybe you have an idea? The right workspace is selected with wifiRSSI.dll and wifidevice.dll in it.

Thanks for your help in advance.

Please give me an example of this bahaviour.

25 Mar 2009 inpoly mex file Find points inside or on the border of a polygon Author: Sebastien Paris Saleh, Korea Univ

some points are on the edges of the polygon and the function can not detect that. what is the reason?

25 Mar 2009 2D Multiwall model A fast implementation of the Multiwall model Author: Sebastien Paris Paris, Sebastien

I don't understand your question. You have just to run the demo file 'test_multiwall_model.m'. data_mw is matlab data file. You can load it with the command load.

hi
please how i make the (data_mw), the file appeare as winap medea player file.can you clear me that?

so thanks.

Very fast!!! well done.

I thing I found an error in the demo file:
The second demo model is buggy: the polygon is self-interecant!!

Very useful. On the examples I have tested, the current mex version of inpoly is about 2 times faster than the *.m file.

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

08 Mar 2009 Particle Filter Color Tracker Tracking an object in a video with a Color Particle Filter Author: Sebastien Paris 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

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

08 Mar 2009 Multitarget Bearing Only Tracking by Particle Filter A demo illustrating Multitarget BO tracking by particle filter Author: Sebastien Paris Zhou, Cong

I also add :"#define max(a,b) ( (a) >= (b) ? (a) : (b) ) " to part_moment.c
now it works~~3q~

07 Mar 2009 Multitarget Bearing Only Tracking by Particle Filter A demo illustrating Multitarget BO tracking by particle filter Author: Sebastien Paris Paris, Sebastien

Please uncomment #define max ..... line in the top of the particle_resampling.c file

07 Mar 2009 Multitarget Bearing Only Tracking by Particle Filter A demo illustrating Multitarget BO tracking by particle filter Author: Sebastien Paris Zhou, Cong

when I run mexmeFIRST , I find this error :

  C:\PROGRA~1\MATLAB\R2007A\BIN\MEX.PL: Error: Link of 'particle_resampling.mexw32' failed.

why this happens?

Hi,

thank you very much for the fast reply!

Unfortunately I still get NaNs in all elements of the em_ghmm results (command: [logl , PIest , Aest , Mest , Sest] = em_ghmm(Ztrain , PI0 , A0 , M0 , S0 , options);).

Maybe these information are also useful:
I needed to add

#define max(a,b) ( (a) >= (b) ? (a) : (b) )

in some of the files (also in em_ghmm.c) to overcome the error

undefined reference to `max'

With this addition, everything compiles fine, with a warning when I compile ndellipse.c:

ndellipse.c:138: warning: assignment discards qualifiers from pointer target type
ndellipse.c:165: warning: assignment discards qualifiers from pointer target type
ndellipse.c:205: warning: assignment discards qualifiers from pointer target type

But as far I can see, the ndellipse function is not used until the first call of em_ghmm in the fest file test_em_ghmm.m.

17 Dec 2008 EM_MVGM Fast implementation of EM algorithm for multivariate gaussian mixture Author: Sebastien Paris Paris, Sebastien

Have you tried by recompiling as this script below ?

echo on
mex em_ghmm.c
mex -Dbetanormalize forward_backward.c
mex likelihood_mvgm.c
mex ndellipse.c
mex -DranSHR3 sample_ghmm.c
echo off

Never tried on 64 bits system
