How to use OPENCV library

TheArkhangel · Sep 25, 2011

Greetings to all.

I am interested to know if I can use the OpenCV library for image processing basic4android.

It can be used directly, anyone know any examples of how to do it?

You can import or create the library to use it directly?

I hope someone can answer these questions.

Regards to all.

Any news about openCV porting to B4A ?

Hello,
I'm resurrecting this oldish thread.

What is the current state for using the the OpenCV library within B4A?

I have a need to locate features within an image. I think the feature detection within OpenCV might be helpful.

Specifically I need to locate the rectangle containing a barcode within the image of a the face of a shipping box.

My first guess is that I need to locate the barcode using feature detection, then using the ABZxing library decode the barcode.

Is there something else I should be looking at? What is the state or possibilities for integrating OpenCV?

Thanks,
Barry.

I too would like to locate features within an image and would like to use something like the SIFT algorithm Scale-invariant feature transform.

Any updates?

Thanks
Kevin

Has there been any further development on this yet?
