Vision-Based Defect Classification and Weight Estimation of Rice Kernels

no code implementations6 Oct 2022 Xiang Wang, Kai Wang, Xiaohong Li, Shiguo Lian

To compensate for the imbalance of different kernel numbers and classify kernels with multiple flaws accurately, we propose a multi-stage workflow which is able to locate the kernels in the captured image and classify their properties.
