Abstract: Aspects of the present disclosure involve a system comprising a medium storing a program and method for machine-learning based selection of a representative video frame. The program and method provide for receiving a set of video frames; determining a first subset of frames by removing frames outside of an image quality threshold; determining a second subset by removing frames outside of an image stillness threshold; computing feature data for each frame in the second subset; providing, for each frame in the second subset, the feature data to a machine learning model (MLM), the MLM being configured to output a score for each frame in the second subset of frames based on the feature data, the MLM having been trained with a first set of images labeled based on aesthetics, and with a second set of images labeled based on image quality; and selecting a frame based on output scores.

Abstract: The invention relates to a device for cleaning and/or disinfecting a teat of an animal immediately prior to or subsequent to the milking operation. The device comprises a teat receiving cup having a plurality of spray nozzles disposed on its upper side which are connected to receive cleansing fluid or disinfectant or both under pressure and capacity control to spray the animal's teats. The spray nozzles and supply lines thereto are affixed to the teat receiving cup so that the nozzles are pointed obliquely upwardly towards the center line of the teat receiving cup. The supply lines, including a distribution member for dividing fluid being conducted to the spray nozzles, is connected to the teat receiving cup by means of an elastic stocking or a shrink stocking.
