Judging the ripeness of a durian (a tropical fruit) by tapping it is done by analyzing the vibration signals produced when the fruit is knocked.
The TinyML-based durian ripeness detection system is designed to determine the ripeness of durians by analyzing the time-frequency features of the vibrational responses, without cutting them open.
This process avoids product waste, provides instant analysis results, and is suitable for large-scale screening. This technology has been increasingly applied in agricultural sorting and fresh food retail scenarios, making it a typical example of acoustic nondestructive testing used for assessing the quality of agricultural products.
