【摘要】 图像边缘提取是图像拼接中常用的一个重要的特征。随着CAD技术的发展,鞋帮图像库变得越来趣大．使得特征的自动提取显得越来越重要。然而在大图像库中．每幅图像的前景和背景间的变化均不相同,自动提取边缘过程中.不同图像边缘的阈值选取非常关键。为实现鞋帮太图像库中图像边缘的自动提取,阈值的动态调整是很重要的。本文提出的动态阈值调整法．能够自动提取各种变化不同的图像边缘。更多还原

【Abstract】 Image edge is an important feature in image splice. As the development of technology of CAD, the upper image database is becoming larger and larger, and it become more and more important to get the features automatically. But in large upper image database, as the changes between foreground and background are various in every image, it is difficult to get the threshold dynamically. In this paper, A method to get the dynamic threshold of all image edges Is presented. It can automatically extract edges of every image in the upper image database.更多还原
