摘　　要：利用X射线成像技术和图像处理技术,对板栗是否有病害进行检测.首先利用3×3高斯滤波器对板栗图像去噪,运用自适应阈值法分割板栗病害区域,再通过分析样本病害区域面积,设定判定阈值,实现板栗是否有病害的定性判别.该判定阈值总体误判率为8.2%.研究表明,X射线成像技术结合图像处理技术,可以实现对板栗品质的无损检测.Qualitative discrimination of disease chestnuts was completed by X-ray imaging and image processing.First,noise of chestnuts′ X-ray images was removed with 3×3 gaussian filter.Then chestnuts′ disease regions were segmented with adaptive threshold.At last,through analyzing area of disease regions,a decision threshold was set.With the threshold,qualitative discrimination was completed,and the ratio of error discrimination was 8.2%.It shows that X-ray imaging and image processing can be used to detect chestnuts internal quality.
