自然场景下树上柑橘实时识别技术（Real-time Recognition of Citrus on Trees in Natural Scene）
柑橘 图像识别 分水岭分割 最小二乘圆拟合
2010/2/26
采用G-B色差分量，通过Otsu自适应阈值分割算法分割成熟柑橘图像，采用基于距离变换的分水岭分割将遮挡、重叠柑橘逐个分开，利用凸包算法修复遮挡区域，设定圆度阈值去除误分割区域，然后提取柑橘轮廓，并运用基于Tukey权重函数的最小二乘圆拟合特征圆，提取了柑橘的中心坐标及半径。对87幅图像中592个柑橘进行了识别试验，总体识别率达87.2%，遮挡或重叠柑橘识别率均超过80%。Using the gra...
