Description: Hough变换用来在图象中查找直线。它的原理是：假设有一条与原点距离为s，方向角为θ的一条直线，直线上的每一点都满足方程 s=x*Cosθ+y*Sinθ，利用这个事实，我们可以找出某条直线来。这段程序，用来找出图象中最长的直线。-Hough Transformation is used for searching lines in an image . Here is the principle:
Assume there is a line whoes direction is \"sita\" , and the distance from the origin to this line is s. So each point in this line satisfies the equation : s=x*Cos(sita) + y*Sin(sita) . We can find out the lines based on this fact.
And this programme is to find out the longest line in the image. Platform: |

Description: 这是一篇关于椭圆检测的文章:对于做人脸识别,模式识别的同行应该会有所帮助.找了好久,才下到,上传来共享下.-abstract:The Hough transformation can detect straight lines in an edge-enhanced picture, however its extension torecover ellipses
requires too long a computing time. This correspondence proposes a
modified method which utilizes two properties of an ellipse in such a
way that it iteratively searches for clusters in two different parameter
spaces to find almost complete ellipses, then evaluates their parameters
by the least mean squares method. Platform: |

Description: Hough变换是图像处理中从图像中识别几何形状的基本方法之一。Hough变换的基本原理在于利用点与线的对偶性，将原始图像空间的给定的曲线通过曲线表达形式变为参数空间的一个点。这样就把原始图像中给定曲线的检测问题转化为寻找参数空间中的峰值问题。也即把检测整体特性转化为检测局部特性。比如直线、椭圆、圆、弧线等。
-Hough transform image processing image recognition from the basic geometry of one of the methods. The basic principle of Hough transform is to use point and line duality, the original image space, the curve of a given expression through the curve into a parameter space of a point. This put the original image in the detection of a given curve is transformed into a parameter space to find problems in the peaks. That is to detect the overall characteristics of transformation for the detection of local features. For example a straight line, ellipse, circle, arc and so on. Platform: |
