     Scale space filter can restrain noise and recognize edge reliably in big scale, and can confirm positions accurately in small scale, at last get the true positions of edge by focus processing from big scale to small scale. But traditional Canny arithmetic based on Guass scale space have shortcomings such as big computing and confirming positions inaccurately.
     尺度空间滤波能在大尺度下抑制噪声可靠的识别边缘,在小尺度下精确定位,最后由粗及精地进行边缘聚焦而得到边缘的真实位置,但是传统的基于Guass尺度空间的Canny算子计算量大,定位不够精确。

     But edge has much bigger energy and range than those of noise and it will become blurry after smoothness, so filter may be used in yardstick area, where noise can be reduced and edge is distinguished. Position is carried out in little yardstick, then focus is made to gain the actual position of edge;
     但是,噪声与边缘显著区别是边缘有较大的能量和范围,在平滑滤波作用下表现为模糊化,因此可以在尺度空间里采取滤波的办法,即在大尺度下抑制噪声,可靠地识别边缘,在小尺度下精确定位,再由粗到细地进行边缘聚焦,得到边缘的真实位置,基于小波变换的多尺度方法就很好的能满足上面的要求,并能提供边缘的尖锐或平滑程度的估计。

  edge focusing
Edge focusing is a coarse-to-fine edge tracking algorithm for recovering the edge points at the finest scale.
      
However, using the edge focusing we were able to recover the edges and tops of the trees, which would be important for the image registration.
      
These algorithms use a method of edge focusing to extract edges and region segmentation based upon minimum line description.
      
Therefore, if 2 = 0.5 in the edge focusing, the displacement of the ramp edge corner would be less than one pixels.
      
Then we applied the edge focusing with the scale step 0 and the varying size windows.

In this paper, we proposed a new implementation method of adaptive focusing, By directly find numerical solution of the diffusion equation, we avoid the convolution operation. The detecting time is shorten greatly. Another advantage of the new algorithm is that the focusing operation can be performed dowa to edge image without any smoothing and make accurate edge detection possible.

本文提出了一种实现自适应边缘聚焦的新方法;通过直接对扩散方程进行数值求解,避免了高斯卷积操作,从而极大地提高了检测速度。新算法的另一个优点是,聚焦操作可以一直进行到无平滑边缘图象,实现了精确的边缘检测。

In this paper the method of detecting and extracting edge features of an image by means of edge focussing is discussed, which can not only ensure the edge positioning accuracy but also constrain the irrelevant image detail and noise
