Claim 0:
1. A system for feed monitoring in a land-based fish farm having a tank containing fish and an effluent pipe that is coupled to the tank where uneaten feed pellets and non-pellet objects flow through the effluent pipe to an exit port, the system comprising:
a feed camera configured to capture a video feed comprising images of an interior of the effluent pipe including objects that traverse a field of view of the feed camera when each image is acquired, the objects comprising the uneaten feed pellets and the non-pellet objects; and
a computing device comprising at least one processor and a memory unit in the form of a non-transient computer-readable medium having stored thereon instructions that when executed cause the at least one processor to perform steps of:
obtaining several images from the video feed for a given time interval;
preprocessing the images 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 a pelletness score representing a probability that the object that corresponds to the candidate ROI belongs to a feed pellet class;
determining whether to retain the candidate ROIs based on a probability that the retained candidate ROI is more likely to belong 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.
