I tested opencv on beagleboard for onboard image processing. The examples provides with opencv runs fine , but the performance is poor compared to a PC.BeagleBoard (OMAP 3530, ARM Cortex-A8 600MHz, 128MB ram)
PC (Intel core2duo 2.13GHz, 1GB ram)
It took me about 4.4 sec on beagle for a simple facedetect example to detect all faces and around 0.35 sec on PC

A few questions:
* Are you really running 600MHz?
* Are you making use of NEON via the compiler?
* Have you looked at using a compiler that better optimizes NEON code than GCC (which is not very good yet)?
* Are you using the DSP for inner-loop functions?
* Are you using single-precision for all floating-point operations?
I hope that you'll recognize that the OpenCV library came from Intel and has already been optimized on that architecture. I hope that you will join the developers optimizing that library for ARM Cortex-A8 and OMAP3 (including C64x+ and more).
Hi, I compiled the OpenCV for ARM (for the iPhone) and the cvHaarDetectObjects does not work, did you do something special during the linking for the ARM processor ?
Hi Vijay,
I am playing around with BB for some time now. Facing a couple issues:
1. The USB OTG port doesn't seem to recognizing any peripheral. I did check the cable and it seems to be the correct configuration. I am in Bangalore, where did you get ur OTG cable from ?
2. I am trying to get OpenCV working on BB as well. Can you share openCV binaries for BB ?

Hi Satendra
1) OTG has mini-A (not mini-B)?, 4th and 5th pins should be shorted. I got mine from ebay.com.(I couldn't get the cable anywhere in chennai)
2) the problem can be that beagleboard can only 1.8v output, try connecting a external powered usb hub.
3) check with "dmesg"
4) lastly check is usb otg host is enabled in kernel
Hi Vijay,
I've just got acquainted with OpenCV and there's a face recognition algorithm I'd like to run on the BB.
I'm working on windows....and all the documentation I've read is based on linux...could you point me to how I can get my program running on BB...And what about the xml files...any processing issues? Did you have to translate the opencv libraries...I'd really appreciate some help.
Thanks,
Saurajit
@Jadon Where are those people optimizing OpenCV for OMAP and others? Is there a sourceforge project or something? What alternative compilers are there?
Hey,
Where did you purchase that Beagle Board?
Thanks
Arvind
plz give ur code.
