摘　　要：由于茶叶容易受到采集时间及环境的影响,是的茶叶的抗活性氧能力不稳定,存在抗活性氧化能力检测效果差的弊端。提出基于反射光谱图像特征测定的茶叶抗活性氧能力判断方法。以模式识别方式完成检测,将图像中每个像素点表示为RGB颜色模型中的向量,建立图像颜色空间的向量模型,利用反射光谱图像特征测定法对茶叶图像颜色的空间向量进行特征测定,获得准确的特征区域向量,从而实现茶叶抗活性氧能力的准确判断。仿真实验结果表明,利用改进的方法,能够获得准确的判断结果,效果令人满意。Because tea easily affected by acquisition time and environment, yes tea reactive oxygen resistance is not stable, disadvantages of reactive oxidation resistance detection effect is poor. Based on spectral reflectance tea reactive oxygen resistance judgment method for the determination of image features. Complete detection in pattern recognition way, each pixel in the image is expressed as the vector of RGB color model, image color space vector model was established, using the reflection spectrum image characteristics measurement characteristics of the tea image color space vector determination, obtain accurate vector feature area, so as to realize the accurate judgment of the reactive oxygen resistance ability of the tea. Simulation experiment results show that the improved method, can obtain accurate judgment as a result, the effect is satisfactory.
