OpenCV image processing captures image and video data on the BBB (Beaglebone Black) with the help of USB webcams by using python script programming. It is simple tutorial where you can also add effects in the form of black and white image, motion detection, sharp picture etc. I have used opencv library which programs functions of real time computer and machine learning. In this project required tools are Webcam and Beaglebone Black.

Nobody had ever thought that Single Board Computers (SBC) apart from their industrial use for embedded systems applications will come to a resort for educating young computer science professionals. The technological advancements removed the necessity of learning bizarre intricacies of the computer architecture and systems. But, soon it was realized that the lack of exposure to such integrated details will be a drawback for the new generation of computer professionals. And then it was the Raspberry Pi foundation that took the plunge. From the time of launch of Raspberry Pi 1 Model B released in 2012 onwards, by now Raspberry Pi 3 has already launched in February 2016.

Although it’s quite similar to a Raspberry Pi yet it comes with some additional features. Developed by a non-profit corporation beagleboard.org, this credit card sized board also supports embedded Linux platform. Due to the presence of so many advanced peripherals, it is also considered to be a minicomputer.BBB consists of core architecture of ARM family and houses AM35X ARM cortex A8 (1GHz) processor. It can be powered either through a micro USB port or an external 5V supply that is present as an optional arrangement.
