摘要
移动图像识别是图像识别中最基本的内容之一。利用轮廓线曲率函数的自相关函数具有图像在移动中不变的特性,用尺度空间来过滤曲率函数——分层次处理图像,从而达到由大范围的特征到细微结构的图像识别过程是判别两个图像相似的有效方法。
Moving image recognition is one of basic substance in image recognition. The autocorrelation function of outline curvature is of invariance in moving of image. Taking advantage of this property, a scale space is used to filter curvature function, then the image is manipulated by stratified sampling from a large scope to a limited range.So it is an effective method to decide whether two images are similar each other.
