Event-Based Vision to Dominate MV Applications?
"Event-based vision is poised to take over from the frame-based approach used by traditional film, digital and mobile phone cameras in many machine-vision applications. The mode of operation of state-of-the-art image sensors is useful for exactly one thing: photography, i.e. for taking an image of a still scene.
An ´ideal´ image sensor samples parts of the scene that contain fast motion and changes at high sampling rates and slow changing parts at slow rates, all at the same time – with the sampling rate going to zero if nothing changes. Obviously, this will not work using one common single sampling rate, the frame rate, for all pixels of a sensor. Conversely, one wants to have as many sampling rates as there are pixel in the sensor – and let each pixel’s sampling rate adapt to the part of the scene it sees."
