Description: 将霍夫变换与最小二乘法相结合,研究对实验数据和图像处理中的二值边缘图进行直线拟合的方法。
首先,用霍夫变换剔除数据点集中的干扰点或噪声,并将分布在不同直线附近的点分离出来 然后,用最小二乘法
拟合各直线。该方法既解决了直接使用最小二乘法拟合时,拟合直线易受干扰点或噪声的影响和数据点分布在
多条直线附近而无法拟合的两个问题 同时也解决了直接使用霍夫变换时,拟合直线精度不高和直线段有效区间

First of all, the use of Hough transform concentration of data points removed or noise interference, and a straight line in the vicinity of different points separated and then, using the straight-line least square method. This method not only solved directly when using the least square method, fitting a straight line susceptible to interference or noise and data points are located in the vicinity of more than a straight line and the two issues can not be fitted while also addressing the direct use of Huo Cardiff transform, the accuracy of fitting straight line segments is not high and the effective range is not easy to control.

Description: 一个空间点P绕一个中心点C旋转可用接续的三个变换来实现：第1个变换平移点C到坐标系原点位置，第2个变换将点P绕原点旋转，第3个变换平移点C回到其相对于坐标系原点的原始位置。当原始图像点乘以变换矩阵，得到新的图像位置点时，其位置可能不是整数值，该位置的灰度值需要通过灰度插值获得。在不改变输出图像大小的情况下，超出原始图片范围的区域，MATLAB原有函数imrotate的处理方法为将其灰度值全部置零，本文通过取模操作对超出区域进行了另外一种控制方法imrotate_my函数，能够较好的显示出图像旋转的边界变化。

Description: ASM是由Cootes和泰勒推出的多分辨率方法的一个例子。
基本思想：
在ASM模型训练，训练从手工绘制的图像轮廓。发现的ASM模型在训练使用主成分分析（PCA），使该模型自动识别数据的主要变化是，如果可能的轮廓/好的对象的轮廓。还包含了ASM模型的协方差矩阵描述行垂直纹理口岸时，在正确的位置。
-Description This is an example of the basic Active Shape Model (ASM) as introduced by Cootes and Taylor, with multi-resolution approach.
Basic idea:
The ASM model is trained from manually drawn contours in training images. The ASM model finds the main variations in the training data using Principal Component Analysis (PCA), which enables the model to automatically recognize if a contour is a possible/good object contour. Also the ASM models contains covariance matrices describing the texture of the lines perpendicular to the control points when in the correct positions.
After creating the ASM model, an initial contour is deformed by finding the best texture match for the control points. This is an iterative process, in which the movement of the control points is limited by what the ASM model recognizes from the training data as a "normal" object contour.
