Systems and methods for monitoring turnover performance

A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A motor assembly is mechanically coupled to the wash basket for selectively rotating the wash basket and a camera assembly is mounted within the cabinet in view of the wash chamber. A controller is configured to obtain a series of image frames using the camera assembly during a wash cycle, identify a tracking point on a clothing article, generate a motion path of the tracking point over the series of image frames using an optical flow technique, estimate a turnover rate of the load of clothes based at least in part on the motion path of the clothing article, and implement responsive action in response to determining that the turnover rate falls below a predetermined threshold rate.
