Claim 13:
14. A computer-implemented method for feed monitoring in a tank of a land-based fish farm, the method comprising:
reading image frames and associated meta-data from a video feed obtained from a feed camera for a given time interval where the image frames obtained by the feed camera are images of uneaten feed pellets and non-pellet objects that are expelled via from the tank;
preprocessing the image frames to obtain candidate regions of interest (ROIs) that each correspond to unique objects in the images where the objects are potentially feed pellets;
performing classification on the candidate ROIs to obtain pelletness scores representing a probability that the objects that correspond to the candidate ROIs belong to a feed pellet class;
determining, using program instructions stored on a memory unit, whether to retain the candidate ROIs based on a probability that the candidate ROI belongs to the feed pellet class;
assigning each of the retained candidate ROIs into trajectories;
classifying the trajectories into pellet trajectories or non-pellet trajectories; and
generating in real time a pellet count based on the pellet trajectories where the pellet count represents a predetermined percentage of the uneaten feed pellets that were not consumed by the fish in the tank.
