摘要
用Pulnix公司的CCD摄像头对缺素黄瓜叶片进行活体采样,并对缺氮、缺镁及正常3种样本的颜色特征与纹理特征随缺素时间变化进行了分析,提出了用灰度共生矩阵法对黄瓜缺素叶片进行纹理特征分析,经试验验证,此方法能有效地区别出纹理特征 在RGB和HSI颜色系统中对黄瓜叶片颜色特征进行分析,B方差、R均值和H(色调)能较好地区别缺氮与正常。
The photoes of nutrient deficiency (N, Mg) and normal samples of live cucumber leaves were taken by CCD camera. The changes of color and texture of these samples were analyzed with time variation. The gray co-matrix to analyze textures features of cucumber leaves was proposed. The RGB and HSI system were applied to extract the color features. It was found that B variance, R means and H(Hue) could extract effectively color features.
