Hi Jinesh,
thanks for your feedback, you are welcome :)
It seems you are not including ehci.h correctly, since it cannot find the
definitions. Where are you compiling the code? Are you sure you have included
ehci.h as a header of your project?
You got a cool use for the project, but I'm afraid it's only going to work if,
at some point, the people in the video face the camera so it can bootstrap.
Please write back,
best regards,
Daniel

Hey Daniel,
Thanks for the reply.
I have copied the file ehci.h in the folder of the source file.
I have included the file in the header of the project. I also included the lib
folder containing this file in the Tools>Options..>etc...include option!!Still
the same errors.
Yes. That was one thing I noticed in the executable version of your code that
once the frontal view was lost, it caused errors in the animated face
orientation. That was the next thing I wanted to discuss with you actually.

Jinesh

Hi Jinesh,
I'm assuming you are using Visual Studio, ok?
So, you should right click your project, properties.
In the Configuration Properties, on the left, C/C++. Now, look for a line
called "Additional Include Directories", on the right.
Click the "..." and make sure you add the folder in which ehci.h is located.
Now, your include errors should be gone.
About the frontal view problem, well... this is an hypothesis of this approach.
It considers the user will face the camera at some point. So, if you cannot
make sure it's true for the videos you are using, chances are this is not the
best approach for what you are looking for. But I'm open for discussing other
ideas.
Best regards,
Daniel

Hey Daniel,
Yes. I am using Visual Studio 2008. I followed the procedure you have given.
Unfortunately that still doesn't seem to solve the errors. !!??!!
About our other discussion, the subject in the video does surely provide a
frontal face at many times in the video. So that's fine. But there are times
when the head is turned more than 90 degrees on either side of the frontal
view. In those situations, the estimation loses accuracy. But the subject
surely comes back. From your executable, I feel that this problem can be solved
if we can somehow do the re-initialization automatically.
Thanks and Regards,
Jinesh

Hey,
I realised the stupid mistake that I have done. Or rather, the step that I have
not done. I have not installed EHCI 0.6 itself. Basically I havent done any of
the steps in the Install file as below.
Installation instructions for EHCI 0.4
--------------------------------------
In order to install the library, go to the directory in which you've copied the
ehci-0.4.tar.gz and issue the following commands:
% tar xvfz ehci-0.4.tar.gz
% cd ehci-0.4
% ./configure
% make
Now, log as super user, go to the ehci-0.4 directory and run
% make install
This is the explanation of the commands:
% tar xvfz ehci-0.4.tar.gz # unpack the sources
% cd ehci-0.4 # change to the toplevel directory
% ./configure # run the `configure' script
% make # build EHCI
% make install # install EHCI
I am installing this on Windows. DO you have instructions for Windows? Kindly
send it quickly, or let me know what I need to do. I think this should solve
the problem Ive been having. (Stupid me)

Hi Jinesh :)
Well, these instructions are for ehci-0.4. I recognize they should have been
updated, but here goes the instructions:
1- Download and install CMake: http://www.cmake.org/
2- Open the cmake-gui
3- On the "Where is the source code:" point to the place where you have
downloaded and extracted ehci-0.7 source (find it here
http://ehci.googlecode.com/files/ehci-0.7-src.zip in the downloads section, I
have just updated)
4- On the "Where to build the binaries:" choose your preferred place to
generate solution files
5- Click "Configure" and choose your installed compilers, and then Finish
6- Chances are you'll get an error in configuration process. It's ok, let's fix
it
7- CMake hasn't found your directories for OpenCV and GLUT. For OpenCV, just
browse to it, in case you have it installed. Else, go to sourceforge and grab
it, install, and then point to it... it's usually at "C:/OpenCV2.1"
8- For GLUT, on windows, you will need to point to Nate Robins binaries (google
for Nate Robins glut), http://www.xmission.com/~nate/glut.html . Download and
extract the bin version. And then, point GLUT_INCLUDE_DIR to
Downloads/glut-3.7.6-bin/glut-3.7.6-bin and GLUT_LIBRARY to
Downloads/glut-3.7.6-bin/glut-3.7.6-bin/glut32.lib
9- Check the "Build_opengl_samples" for some fun
10- Hit configure again... you'll see some warnings and then something like:
"Looking for GLUT
Looking for GLUT - found : C:/Documents and Settings/Administrator/My
Documents/Downloads/glut-3.7.6-bin/glut-3.7.6-bin
Configuring done"
11- Well done, hit "Configure" again, and then "Generate". You should see:
"Generating done"
12- Congratulations, now you have all the solution files (in case you are with
Visual Studio) so you can open then and change them as you wish. Go to
"\ehci-build\samples" and open the boxView3d.vcproj, for instance. Click
"Build->Build Solution" and Visual Studio should generate the executables on
"ehci-build\samples\Debug". You should just go there and double click
boxView3d.exe, for instance. And then, you might get something like: "This
application has failed to start because cxcore210d.dll was not found". It means
your opencv dlls are not on the path... a fast way to find them is copying all
dll files from "C:\OpenCV2.1\bin" to your ehci-build\samples\Debug" folder.
13- Double click them again and then... oops, glut32.dll might also be missing.
Just copy it there as well (or send to your system32). Remember that it comes
from Nate Robins glut binaries, there's a file at
"glut-3.7.6-bin\glut-3.7.6-bin\glut32.dll".
14- Almost there... now your executable is looking for data files... which are
back in your ehci source folder: "\ehci\data". Just copy the whole directory to
your samples\Debug and then... almost there... your data\config.ini might be
trying to open some trash. Just make sure it looks like this:
USE_RANSAC 1
RANSAC_SAMPLES 6
RANSAC_DISTANCE_THRESHOLD 30.0
RANSAC_ITERATIONS 20
CAMERA_INDEX 1
OPEN_MOVIE NO
Edit and save it, go back to boxview3d.exe and double click it :)
Voilà... you should see the 3d cube moving as your head moves. Check out the
other samples, make changes and write back in case you had any other problems.
Thanks for posting your doubts.

Hello, I am getting similar errors when Im using Ehci. I am trying to use ehci
along with Kinect XBOX visual camera. I am running it on linux. I have openNI,
ehci and opencv installed. When I try to compile using the following line:
g++ main.cpp -I/usr/include/nite -I/usr/include/ni -I/usr/local/include
-I/usr/local/include -lOpenNI -lGL -lGLU -lglut -lehci `pkg-config --libs
--cflags opencv` -lEGL SceneDrawer.cpp HeadTracker.cpp opengles.cpp -o trial
I get the following errors:
HeadTracker.cpp: In function ‘void keyframeRelated()’:

Can you please help?
Thank you,
