中文摘要：

在甘蔗病害识别的研究中,为寻找合适的赤腐病病斑和环斑病病斑分类的特征参数,从颜色、纹理和形状3个方面探讨了识别这两种病斑的特征参数的可行性。初步分析结果表明：颜色分量Cr的均值、颜色分量S的方差、颜色分量V的均值、圆度和复杂性可作为识别这两种病斑的特征参数。用模糊K-近邻算法进行模式识别,结果发现颜色分量Cr的均值与圆度、颜色分量V的均值与圆度的特征参数组合的区分效果最好。

英文摘要：

The suitable feature parameter for the recognition of sugarcane red rot diseased spots and ring spot diseased spots should be received in the research of the recognition of sugarcane diseases. The feasibility of the feature parameters for recognition of the two spots is discussed from color,texture and shape. The preliminary analysis results show that mean value of color component Cr, variance of color component S, mean value of color component V, roundness and complexity can be used as the feature parameter for recognition of the two spots. The results show that the recognition effects of the feature parameter combinations of mean value of color component Cr and roundness, mean value of color component V and roundness are best in fuzzy K near neighbor algorithm.
