Abstract:

The article first outlines two methods of image acquisition, namely, the capture of RGB images and spectral images. Subsequently, it explores image preprocessing techniques, including steps such as image denoising, enhancement, and segmentation. In terms of feature extraction, principal component analysis (PCA) and linear discriminant analysis (LDA) methods are employed to efficiently extract the color, texture, and shape features of rice seeds. Additionally, the article discusses the practical applications of machine learning and deep learning in processing spectral and RGB images of rice seeds, as well as the performance optimization and improvement methods of deep learning models in rice seed recognition and classification. Overall, machine vision technology demonstrates its efficiency and accuracy in the field of rice seed recognition. In the future, the development of a low-cost image acquisition platform and more lightweight rice seed recognition software can be anticipated, promoting rice seed data sharing and continuously exploring emerging deep learning techniques to further optimize the effectiveness of rice seed recognition.
