基于计算机视觉的稻谷品种数据库检索技术

Image Retrieval of Rice Varieties Database Using Computer Vision

利用计算机视觉技术提取稻谷的主要外形特征,初步建立了稻谷品种数据库。研究了稻谷品种数据库的检索技术,提出了将BP神经网络与相似度检索相结合的检索方法。实验结果表明,该方法可有效提高检索效率。

A database was established to store external features of rice varieties extracted by computer vision. Retrieval technique of rice image based on content was investigated and a new retrieval method was proposed by combining the BP neural network with the similarity retrieval technique. The tests showed that the new method is of high efficiency both in identification and in database retrieval of rice variety.
