Robotic vision

edit

I have made an indegenious robot with a small notebook , arduino micro controller and a web camera. The notebook has Ubuntu on it which runs node.js (server) and it transmits the video and data attached to the micro controller to the client computer through WiFi. Presently i am using a free software called Yawcam to transmit video. I have two specific questions 1. Is it possible to do video transmission using OpenCV? or if i capture the video using open CV , how will i transmit it using node.js server(websocket server).

1. I want to process the real time video arriving at my client side with OpenCV and based on the results of video processing , the user will give suitable instructions to the robot. is this possible?

Thanks in advance
