mini2440 work in image processing?

Hi I will project the picture processing. Counting the number of cars on
the road with cameras. I want to know. Mini2440 supports that or not using
linux.

Hi Nave

Now I'm working at a project called Eye Tracking System. The main task of
mini2440 is to detect the eye in continuous frames get from a web camera
connected through USB. I'm using an image processing library called OpenCV.
It's manufactured by Intel. I can get a speed of 20~25 fps without any
processing and after processing I get the eye coordinates with a speed of 5
fps. But in your case you will have more computations than me.

I suggest you to develop a part of project (detect a car for example) and
to run it on PC machine. You can monitor the time and you we'll able to
decide if the ARM S3C2440 can perform your computations.

Thank azzido.

I recently began to study. Have to bother with.
OpenCV you use linux on the surface data and the programs you run on the
board of linux mini2440 it or not.

If I do not irritate your e-mail you? Thanks.

Dear all,

I am the same one want to using ARM9 to build project about image
processing.
but i don't have any data of its. 
i will registration the training courses for using it on Linux OS and WinCE
OS. 
I am not sure about possible of the image processing on ARM9 and Is it too 
difficult?

Have you the example project to using this? 
pls. give me at j_phetchuen at yahoo dot com.

Very thankyou.

@Nave: My e-mail address is p.nicusor@yahoo.com

@Naja: It's not so difficult if you use a library for image processing like
OpenCV. But what do you want to do ? Using an USB camera ? You can find a
lot of examples searching on google with "OpenCV example"

You need a good software math processor (aka floating point emulator)
because image processing (especially with motion) mostly needs lots of
calculations to crop, rotate, zoom in/out etc. but the arm9 has no
integrated one as far as I know. There are flying good software floating
point emulators around in the internet. I prefer to use the FastFPE one
(it's not as precise as NWFPE but very fast).

Jay, you right. I used EABI that is included in arm-linux-gcc 4.3.2 from
CodeSourcery.

Hi all,
I'm working on a program to extrapolate gaussian information from the CMOS
camera.
I can get almost 50 fps streaming to video and 20 fps with the maths
running.
I m only on 320 x 240 atm and I need more speed.
Was talking to Vladimir Fonov over the weekend who sent me his driver for
the CMOS camera which is excellent, and he is sending me another one
shortly which does YCbCr and RGB.
Is anyone interested in starting a little page where we can exchange
specific "image processing" information?
Cheers
Paul

Oh forgot :P

I went from 18.7 to 23.54 fps by switching all doubles to floats, unless
you really need the accuracy.
Its easy to do, just do a Replace All "double" with "float" then patch up.
Naturally, this includes redeclaring all decimals as floats:
0.0 -> 0.0f

Works for me
Cheers
Paul

hi guys, i m currently working on image processing. i m using MATLAB for
writing algorithms , i want to know that which ARM9 processor will be
suitable for me . i don't know much more a bout ARM9 , so pls help me out..

Hey Paul,

Mind sharing the libraries? I want to use the setup to do some line
following in a very bright noisy environment.
You can mail me the libs at sidchinoy222 (at) gmail (dot) com

Thanks.

PS: I think the image processing page is a good idea. let's start it!

Hi AZZIDO!
 I'm also doing mmini2440 with image processing and tried to project : Eye
tracking.Before I worked with open CV on my PC, it works well but now, when
I used mini2440,it has many problems. 
   could u help me some questions:
   1> Do i have to rebuild openCV  or not? how to load into board
   2> How to run simple program using library openCV. ( I also write some
simple codes but when building, it doesn't work) .
 Thanks and hope to get ur answers soon
 Nice day!

Paul Matteucci  can you send me your OpenCV source tree so that i can
compile it?  The one I have keeps give me invalif instruction. valdimir
could you share you new driver ?

Thanks all

Hi all

I was wondering how to increase the window size of the usb camera window,
so that it maximizes on the whole screen.Any help will be appreciated.

Thanks

Can anybody send me the OpenCV configuration file for Mini2440 ? My OpenCV
code gives invalid instruction when run and I susoect it is some config
option. I am sure the generated code is ARM but it sitll keeps giing me
invalid instruction.

hi
 I'm doing my final year project using arm9 additionally  i decide to do
image processing mini2440 friendly arm . if anyone having idea about give
suggestion to me as well as if possible give source code for image
processing 
  Thanking you

Hi,
   I am working on real time edge detection using ARM9 mini 2440. Is it
possible to implement C code on ARM9

Hi Shanshank,

Yes it is possible to run edge detection using opencv on mini2440...can
