Abstract
⺠An SWIR hyperspectral imaging system was explored to detect sour skin in onions. ⺠Healthy & infected onions showed distinct spectral characteristics in 950-1650 nm. ⺠Log-ratio images of onions were generated using images at 1070 & 1400 nm. ⺠SVM using image features (max, contrast, & homogeneity) achieved 87.14% accuracy. ⺠The study shows the potential of using spectral imaging to detect onion sour skin.
