Sobel Edge Detection on the Parallella

This program performs Sobel edge detection on a video feed from OpenCV.

Implementation

Host side:

• Controlling and synchronizing the eCores
• Managing frame-buffer, OpenCV
• Transfer grayscale image data to emem

Device(Epiphany) side:

• Get the image data from emem
• Apply the Sobel edge detection algorithm
• After rendering a frame, halt until interrupted by the host.

Building

System requirements:

• Parallella board Gen 1.1 or later
• Parallella Official Ubuntu
• Epiphany SDK 5 or later
• OpenCV compatible webcam
• OpenCV

Install dependent packages:

sudo apt-get update

sudo apt-get install pkg-config build-essential libopencv-dev

Make sure the pkg-config files are available:

sudo wget -O /usr/local/lib/pkgconfig/coprthr.pc "https://gist.githubusercontent.com/sclukey/2969d30e33c6eac57ba2/raw/f749fbbf9a804b5e46849dbfe15e484a11f9d10b/coprthr.pc"
