Hi RobynOkay, finally got a handle on your file.1. You sent me the wrong .cf
file. It did not match the 1t and 2t and 3d. However, I took the .cf file
you sent me and changed the name to match the others. It had three
trim.trim.trim in it and I simply changed it to
trim.cf. I think the real .cf is in your computer but you missed it.
However, the corrected .cf worked well. 2. I was able to view the stick
figure but it was aligned from the top. This is a function of how you set
up your calibration volume. More on this later. 3. I was able to align the
file on the positive x and get a walking figure. It was very rough and you
are right, many kinematic parameters were unavailable. This was due to the
fact that you did not perform filtering on this file. Once filtering is
performed, all parameters are available. So, I opened filter, loaded the
file and hand filtered to the best values. It required around 10-15 mm on
the x and z but 50 on the y. Why?? 4. When I was able to re-load the .cf
and vids on digi, I looked at your calibration volume. It is very low and
not big enough. In display, if you select VIEW/MULTIPLE, you will see
every frame and note your stick figure goes from smaller to larger. This is
a function of being outside your calibration area. As a rule, you need
2/3rds the height of the subject and about 2/3 rds of the walking length.
We do this with a simple rectagular frame. I use 3 meter long by 1 meter
wide by 2 meter high. Your configuration is way to small. Anyway, I sent
you back the corrected file. You should be able to look at it and do
measurements. However, your accuracy will be poor due to the calibration
shortcomings. Let me know if you understand all the above and need further
help on the next pass.Bob
ps- make a new file folder for these corrected files to view from. Also,
if you re-load in digi, use the .trim avi's not the .trim.trim.trim. As to
the name of the file, you decide this yourself. It just defaulted to .cam1
for the name of the project file because you did not create your own name.
This has nothing to do with the names of the .avi files. That is why you
see .cam1 in both t views on the screen.

Hi again Bob
Okay, so my camera's were anywhere from 45-60 degrees apart, hopefully that
is good enough.
If it helps at all, i was getting an error message that said, MJPEG Field
Image Order Undefined, Use Image/Video to set order, but i have not recieved
this message as of late, and i dont think i have been doing anything
different to have changed it
However, I did end up with subject.cam1.trim.1t [subject.cam1.trim.avi] and
subject.cam1.trim.2t[subject.cam2.trim.avi]
So my 1t and 2t seems like its okay, its my cam.1 and cam1 in the titles,
but if that is as you say, irrelevant, than I am not sure why i can't
display 3d data.
I hope these are the right files this time...they are all new from the last
set i sent you
Thank you again

Hi Bob,
Oh sorry!
I didn't realize you were away, I just never heard back and then didn't know
what to think.
Here are a couple of my files. My issue must be something very simple, I
just cant get my head around what.
I can't get 3-D data in the display mode.
I have 2 camera views.
In trimming i open the AVI from each view
In digi. I select 2 views, and put the AVI in each, however that this
point, both camera views that are opened are labeled as cam1. I can't seem
to get one window opened as camera 1 and the other as camera 2. Even though
I can open the AVI from camera 1 and camera 2, they are both get saved (seperately)
as cam 1
Does this make any sense to you?
I am not sure if the files I have attached will show you this problem, but I
hope so.
I seem to go through the digi and transfom modes fine (doing it manually),
but in the end display, i can only select linear displacement (not joint
angle or 3-D which I am intereseted in)
Thank you so much for your assisstance with this finicky problem, I am
blonde and hate to admit it, but sometimes it is the really simple things
that I tend to over look...

Hi Bob
It has been a while since we corresponded. I did eventually send you one of
my files, but have not heard anything back.
Can you please let me know if something is wrong in any respect.
I have been a bit side tracked writing about 100 pages of my 150 page
thesis, but am ready to get back into the technical part of the project
again.
Please do touch base and let me know if there is anything that is not
okay from yours or Gideon's points.
Thank you for keeping me up to date.

Date: Wed, 8 Apr 2009 09:49:19 -0400
Hi RobynSounds like you may have digitized the files individually? At any rate, it does not matter. Something is not quite right. It looks as though you do have your files named correctly. You correct the problem as follows:1. Open the Transform Module. Open your file "subject.cf" It should show two views. Check each view and pres the 3d button on top. This does the DLT. For some reason, your digi program is not letting it be done automatically. After transformation, it will automatically filter the data to a very small degree. You will than be able to perform all functions in display because it will be transformed and filtered. 2. If you want to filter the data by hand (probably a good idea), you can do it through the filter module. Let me know if this works for you. If not, send me the files and I will see what I can do but I am 99% sure this will solve your problem.Bob----- Original Message ----- From: Robyn Brandt To: kincon@bellatlantic.net Sent: Tuesday, April 07, 2009 4:44 PMSubject: RE: dropping frames
Hi Bob,
To give you an update on this whole mess....i replaced my hard drive and
downloaded another version of the software. It is working just fine now. I
also have upgraded my RAM (to 2 GB).
I am now processing all my videos and i hit a snag...if i could trouble you
for one more piece of help?
I have done the digitizing, but i think it is something in the way i am
saving the data that is not stopping me from being able to use the display
option to properly extract the data i need, i'll explain here:
i have 2 camera's, therefore 2 views.
in digi i have them opened as: subject.cam1.trim.1t[subject.cam1.trim.avi]
and subject.cam1.trim.2t[subject.cam2.trim.avi]
in the digi when i click on DLT it tells me i have insufficient views.
also, in the display option i can only extract the raw position (not joint
angle etc which i want to use)
Can you see where i am wrong. i am using the 2 different avi files, but
both views are named for the camera 1...how do i correct this? this didnt
happen the first time around when i did my pilot study, so i am not sure
where i have missed up, but i have spent a few hours trying to play around
wiht it....
and lastly, are you aware of any 'gold standard' so to speak about these 3d
video imaging programs? or specific peer reviewed articles that reference
them (not just the ariel, but any...as in what is the gold standard, is
there one?)
Any help is appreciated....and very much so already to this point
Thanks,
Robyn

Hi RobynRe: computer- I would save my money on computer check and re-loading the disk. It sounds like you do indeed have a problem with the hard disk itself. If it were me, I would buy a new hard drive for the computer, load from scratch and go from there. I believe this would be the cheapest solution. Your study sounds great. I would love to see your results when finished. Best of luck with it. Let me know how the solution for the computer goes, when you determine what to do.RegardsBob----- Original Message ----- From: Robyn Brandt To: kincon@bellatlantic.net Sent: Wednesday, March 18, 2009 10:10 AMSubject: RE: dropping frames
Hi Bob
Thank you AGAIN for the help...here are my answers
1. If i use one camera i drop less frames, but still drop them
2. When the problem originally started, just prior to it, i had created a
new folder save a copy of the temporary files (as i had not saved any to
drive yet!) and recieved a messsage that there was a problem with my hard
disc the next day. I then followed a 5 step prompt to do a systems check on
my computer and everything came out okay. since then i have done all the
defrag etc, but not prior to.
3. I have borrowed my sisters laptop to finish off my study, reloaded APAS
on it and it is working just fine, so its obviously on my laptop...I am
going to look into doing one of the two options of wiping things clean or
taking it in...just not sure yet. I have been recently getting an error
report every single time i close my internet browser screen, something is
not right for sure
As for my work, I am almost (hence doing my thesis) an osteopath. I am a
student in osteopathy but do some teaching at massage therapy schools, and
may consider once i am done my thesis teaching at the osteopathic schools if
there is a opening for me.
My work is to determine if osteopathic techniques can influence the body in
three-dimensional parameters (center of mass, segment joint angles etc.)
It is quite a small and unique field and i have undertaken this giant
project all on my own!
I really hope to find some significant results, although I am not sure what
the statistics will show yet, i did a pilot study which showed a positive
trend, but still have to see.
Much of osteopathic work is treating various organs/bones/softtissues in a
very volumetric and three-dimensional manner, so to me there should be a way
to marry the two ideas.
Thanks again, I hope this helps for some info

Hi RobynLast thoughts:1. Can you successfully capture one camera without dropping frames, if so, up to how long?2. When you lost the abiilty to capture two without dropping, did something else occur with the computer at that time? (loading new software, etc.) 3. Last but least, I still think you have a software, adware, virus problem that you are not detecting. We know your computer is fast enought, 1gb ram is adequate for two cameras, you did it before, it will work okay on the next computer (unless your cables have a problem, which you will find out soon). After this next correspondence, you may have to take it in to a computer expert to see if your registry is congested or you have some other problem. Instead of spending a lot of money on a cleanup, you can also consider the following: backup your files, wipe the hard disk and re-load XP from scratch. Just for my curiousity, what kind of work are you doing with APAS? Are you a student or teacher? What is your specialty? I am in Point Pleasant, NJ and have successfully used APAS for over 24 years for sports medicine, workers compensation and physical therapy. I am curious about what you do because there may be some things we can talk about from a business prospective for your future activities. Of course, you do not have to share any information with me, that is entirely up to you.RegardsBob----- Original Message ----- From: Robyn Brandt To: kincon@bellatlantic.net Sent: Tuesday, March 17, 2009 5:02 PMSubject: RE: dropping frames

Hi RobynIf you are trying to send temp .avi files upon capture to the external hard drive it may be too slow. That is why I suggested using the C or D drive on the laptop for the temp files and the external to store them (if you do not know what I mean here, please let me know). The USB cables work fine at 15 feet. You probably do not have to defrag the external but make sure you defrag every drive on the internal. If all the suggestions fail, I am thinking perhaps you may have developed a problem with the internal hard drive. Anyway, please try what I am suggesting and see if it makes a difference. Please let me know. RegardsBob----- Original Message ----- From: Robyn Brandt To: kincon@bellatlantic.net Sent: Monday, March 16, 2009 9:16 PMSubject: RE: dropping frames

I did not defrag the external drive, should i? its brand new basically.
I have usb cables that are under 5 feet and my subjects are within 15 ft for
the most part. I am now trying to download the software on a new computer
and start over basically...
I could try a signal booster, but its not even working at close range in
some trials.

Hi RobynOkay, that is one more clue. If you use usb2, you are only good for 5 meters. After 5 meters, you need a signal booster on the cable. They sell these for only a few more dollars than the 5 meter cable. I have many installations where I use this configuration. You should have no problem with two cameras on usb2. If your cables are longer than 5 meters, try shorter cables and see if this is the problem. By the way, did you defrage the extra hard drive that you use for data collection. If it is an external, you may have to use the hard drive on the computer for the temp file and the external for the storage, after it is complete.Let me know.Bob----- Original Message ----- From: Robyn Brandt To: kincon@bellatlantic.net Sent: Monday, March 16, 2009 7:38 AMSubject: RE: dropping frames
Hi Bob
Thank you for the email.
I do have an external hard drive that has the video's i have been collecting
on them.
I recently have done a virus scan (so if i have one my computer is not
detecting it), defragmented, and done a disc clean.
The laptop i am using is the same one i do use for the internet,
unfortunately I only have one and this is a one time thesis project for me,
so likely will not be buying a second, although, I may try and borrow one
and download the software again to see if its my computer.
I have not needed firewire, i was on usb 2-enhanced and was collecting the
data just fine, it seems unlikely that if it was working okay before, all of
a sudden i now need firewire, although at this point i am willing to try
anything, is there something i should know about the length of the cable if
i do get them?
Thank you again for your time helping me, these technical blimps can be
very frustrating

Hi RobynI am Robert Wainwright, P.T., long colleague of Gideon Ariel's and occasional tech consultant. I have been following your emails. I would suggest you get a second hard drive and dedicate it to the video data collection only. They are very inexpensive these days. I would have bet on the defrag also. There is also a possibility that you have ADWare or some sort of virus hidden in your system. This will screw up the frame grabbing also. I never allow my data collection computer to go on the internet. It is not logical that it works great and than suddenly does not. I have six cameras collecting data at all times with no dropped frames. Last thought, how long is your firewire cable?RegardsBob
