So, in your case, flow is an opticalFlow object, not a complex array, and you cannot pass it to real and imag. Instead, use the properties of the object:

Webb24 mars 2024 · I am unsure about what you want to classify in the video using the optical flow estimation workflow. As per my understanding the above code estimate the direction and ma gnitude of the movement of any pixel in two consecutive frames. So essentially you can use the algorithm to tell if any object which consists of many pixels is moving or not.
