基于K均值聚类的绿色苹果识别技术（Segmentation Algorithm for Green Apples Recognition Based on K-means Algorithm）
苹果 机器视觉 图像识别
2009/11/3
针对颜色和背景相近的绿色苹果，提出了一种基于K-均值聚类的苹果图像识别算法。该算法以8×8像素的正方形区域为分割单位。选择颜色差R-B作为颜色特征，选择灰度均值m，标准偏差σ和熵e作为纹理特征，形成特征向量空间。采用间隙统计法确定苹果图像的最佳聚类数。 将特征向量空间和最佳聚类数作为输入，运用本文算法对苹果图像进行聚类和分割。对200幅图像识别实验结果表明，在顺光和逆光情况下，算法均能实现果实与背...
