Description

Dong-Hoon Kwak, Ho-Won Yun, Jong-Hun Lee, Young-Duk Kim, and Doo-Hyun Choi published this food safety study in 2024. It describes a machine that inspects seaweed sheets as they move along a conveyor belt. The system uses sub-terahertz waves, which pass through dry, non-conducting material, to spot foreign matter hidden in the product and judge how deep it sits. It also estimates water activity, a measure tied to freshness.

The team trained a light object-spotting model on 9,659 labeled images taken with the system. Their hardware kept pace with a belt moving at 45 centimeters per second. Final scores were strong: precision of 0.91, recall of 0.95, and an F1-score of 0.93. The authors present the setup as a contact-free way to check food safety on a real production line.
