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。
In the image recognition, rectangle as one of the most common man-made shapes, detection of it has a wide applica- tion. An approach Based on edge line detection to extract rectangles in images is presented in this paper. The method firstly ap- plies edge detection on the input image and obtains the edge map; secondly, it performs line detection to the edge map and ob- tains all straight line segments; thirdly, the line segments that satisfy the rectangular feature are combined to extract possible rectan- gles in the image. Experimental results show that the method has better anti-jamming ability, and it is fast and effective.
