【摘要】 在图像识别中,矩形作为最常见的人工图形之一,对它的检测有着广泛应用。提出了一种基于边缘直线检测的矩形提取方法。该方法首先对图像进行边缘检测,得到边缘图像;然后对边缘图像进行直线检测,得到图像中所有的直线段;最后对满足矩形特征的直线段进行组合,提取图像中可能的矩形。实验结果表明,该方法具有较好的抗干扰能力,且运算速度快,是一种有效的矩形提取方法。更多还原

【Abstract】 In the image recognition,rectangle as one of the most common man-made shapes,detection of it has a wide application.An approach Based on edge line detection to extract rectangles in images is presented in this paper.The method firstly applies edge detection on the input image and obtains the edge map;secondly,it performs line detection to the edge map and obtains all straight line segments;thirdly,the line segments that satisfy the rectangular feature are combined to extract possible rectangles in the image.Experimental results show that the method has better anti-jamming ability,and it is fast and effective.更多还原
