Application of Color Features Based on Multispectral Imaging in Rice Seed Vigour Detection
摘要
Abstract
Rice is the staple food crop for more than half of the world's population,and rice seed vigour has a crucial impact on the yield and seed quality.The existing seed vigour detection methods are mainly based on germination test,which is a destructive method.In order to make up for the drawbacks of the existing detection methods,six rice varieties were used as materials,and seeds with different vigour gradients were obtained by artificially accelerated aging treatments for 0,5,10 and 20 days.The multispectral images and color feature data of rice seeds were collected by multispectral imaging system,and the possibility of evaluating rice seed vigour based on color features in multispectral imaging and CIELab color space values in nCDA(normalized canonical discriminant analysis)images was studied.The results showed that the seed germination time of the six rice varieties was prolonged and the seed vigor was decreased after accelerated aging.The changes of CIELab values in multispectral imaging of six varieties after accelerated aging were not obvious,and the correlation between CIELab values and seed vigour indexes was not significant.After the multispectral images were transformed by nCDA,the seeds with different aging time could be distinguished by the nCDA image,and the values of CIELab a* and CIELab b* in the nCDA image were significantly negatively correlated with the four vigour indexes.Among them,CIELab a* had the highest correlation with germination rate,germination potential and germination index,and the correlation coefficients were-0.659 3,-0.651 5 and-0.661 7,respectively,indicating that the CIELab color features based on multispectral imaging had application potential in seed vigour detection.关键词
