This project applies cutting-edge artificial intelligence technology to the smart aquaculture monitor system . With the aid of underwater lenses and various sensors and using machine learning techniques, we are able to generate clear images under the original turbid water and identify fish, shrimp, and bait in acqua-culture ponds. In addition, according to various environmental parameters (remained battery energy, water turbidity, temperature, etc.), the neural network hardware accelerator embedded in the edge devices (camera/sensors) can be dynamically adjusted to achieve low power and real-time processing speed for fish/shrimp/bait detection in the underwater monitor system. Furthermore, the computation results can be used to activate the peripheral control equipment in the smart underwater aqua-culture system.
