hi

i have a parallella video processing project using USB webcam (ARM/epiphany programming)

What are the libraries i have to use to in the project: can i for example use openCV??

Thanks

You can use OpenCV, but by default this will only make use of the host (ARM) for processing.

It was done with pre-Parallella hardware and the SDK will have moved on quite a bit, but you may want to take a look at an early Epiphany-enabled OpenCV demo that Adapteva did as a collaboration with CVisionLab:

This should give you an idea of the extra work required to enable Epiphany offload of compute intensive tasks within OpenCV.

Also, OmerK and his colleagues built a CV system in Erlang, using multiple Raspberry Pi + camera to provide the source video:

Note that if you are looking for a plug-and-play computer vision library with Epiphany support, I do not believe that one exists at the present time. So, you will have to get to grips with the Parallella/Epiphany programming model first, and then extend whatever framework or library you decide to use.

Thanks Andew for these informations

But what about the Kinect test parallella example. Do you think it could be useful for building my ARM/epiphany project
