The present paper presents a new method based on the elliptical model and artificial neural network for estimating the pose of human face.
基于椭圆模型和神经网络方法,提出一种人脸姿态估计方法。
To gain harm degree information of crops disease in real time, this paper studied one method to examine harm degree of the rice blast and the rice sheath blight with ellipse model: used ellipse to fit the biggest sickness spot of the rice blast, calculated the length of principal axis of ellipse and the compared with ma.
为了实时获取作物病虫害危害程度信息,该文研究了一种利用椭圆模型来检测水稻稻瘟病及水稻纹枯病的危害程度--用椭圆拟合水稻稻瘟病单株最大病斑,计算椭圆主轴长与人工检测的实际最大病斑的长度比较,分析两者相关性,结果具有极显著性;同理,用椭圆拟合水稻纹枯病单株高度及病斑最高处距基部的距离,计算两椭圆主轴长并求两者之比即可对水稻纹枯病危害程度进行检测,平均正确率在90%以上。
