Thread Subject: Which programming language should be used for image processing???

I am doing my final year project titled "Web cam for the blind". The
task of the project is to capture images from the webcam and to
process the image and extract useful objects from the images.The
object extracted will be compared to the objects defined in the
database and the appropriate objects audio will be the o/p to the
blind which will help as a navigation tool to the blind.
Now my quetion is that which programming language will the most
efficient to use?
Also is it possible to integrate java with matlab.Any one having any
idea as to how to implement the project will be a great help for us.
Thank you

Use the language you are most proficient and comfortable with.
I would be surprised if run-time efficiency will be the main
obstacle in your efforts; making the object recognition system
work will be no trivial task unless you use very simple test
images.

Check the Matlab API documentation.

Matlab is good for image processing but slow
You can do simulation in matlab and probably code in C++ or
other languages

check out Intel's OpenCV library. it's free and very fast.

If you are intending to use an Intel processor (e.g.
Pentium class device), then in addition to the OpenCV
library look to use the Intel rather than the Microsoft
compiler. I understand that it can be integrated into
Microsoft Visual studio environment. It is excellent at
optimizing the code to use the SIMD and MMX facilities in
the CPU which has a tremendous effect on the execution
performance of many CV algorithms.

If you intend using an ARM or something in a portable unit,
forget my advice.

The starting point in my project is to capture an image and use it for
processing.Can you tell how to capture te image and use it for
processing.Is it possible to image using matlab and use for processing
or do we need to integrate java along with matlab for this purpose or
do we need to use some other language.

For your initial experiments, all you need is

1) Matlab,
2) The image processing toolbox,
3) The image acquisition tool box

Get the information & quotation from The Mathworks

You will also require a PC, with speaker system and a camera
\framegrabber compatible with item 3) check with the
Mathworks (I think - but don't know - that you can interface
a standard USB webcam so you wouldn't need a framegrabber).

Hello,
Here is the code block that you can use to capture images
from webcam by using MATLAB.
---------
obj = videoinput('winvideo', 1);
set(obj, 'FramesPerTrigger', 1);
src_obj = getselectedsource(obj);
get(src_obj)
frame = getsnapshot(obj);
---------
by reading the descriptions of the above functions, you can
easily understand and adapt the codes to your computer. only
thing is that, above functions belong to image acqusition
toolbox and you can find it at r2007b.
