基于小波变换的直线检测

提出了一种利用小波变换来检测图像中直线的方法,对小波变换提取图像直线能力做了理论分析,并利用B样条小波对图像进行多级小波变换,计算变换后模值和幅角,利用Hough变换从高分辨率到低分辨率依次确定图像中直线的位置。试验表明,该方法能快速、准确检测到图像中的直线。

Line Detection Based on Wavelets Transform

This paper proposes a method which bases on the wavelets transform to detect the line in the image,the theory of line detecting based on wavelets transform is analyzed,and the wavelets transform is performed using the B spline wavelets,and the modulus and angle of the transformed image are calculated,then we detect the position of line from high resolution to low resolution using the Hough transform.The experiments show that this method can locate the line position in image fast and precisely.
