摘要
灰度相关法是一种广泛应用的图像识别方法 ,常用在流动图像的解析上 ,而图像质量与流场特性直接关系到图像解析的精度与可信赖度 .
Gray scale correlation method is widely applied in image recognition, generally in analysis of flow image. However, the precision and reliability of image analysis is related to the quality of image and the characteristics of flow field. In this paper the relation between the quality of image and mistake vector as well as the relation between correlation coefficient and flow distortion are mostly discussed. [WX(5KG0,41]
