【摘要】 边缘检测一直是计算机视觉和图像处理领域的经典研究课题之一,它是图像处理、图像分析、图像模式识别和计算机视觉研究的基础,其结果的正确性和可靠性将直接影响到机器视觉系统对客观世界的理解。传统边缘检测方法只能达到像素级精度,本文采用曲线拟合的方法对玻璃瓶的图像边缘进行检测,可使边缘检测达到亚像素精度。更多还原

【Abstract】 Edge is one of the most fundamental and significant features.Edge detection is always one of the most classical studying projects of computer vision and image processing field.It is one of the fundamental steps in image processing,mage analysis,image patter recognition,and computer vision,as well as in human vision.The correctness and reliability of its results affect directly the comprehension machine system made for objective world.This article adopts the method of curve fitting to make image edge detection of glass bottles getting the sub pixel accuracy that can’t be achieved by the classical edge detection methods and making the edge detection reach the sub pixel accuracy.更多还原
