Description: OTSU方法计算图像二值化的自适应阈值,OTSU 算法可以说是自适应计算单阈值(用来转换灰度图像为二值图像)的简单高效方法。下面的代码最早由 Ryan Dibble提供,此后经过多人Joerg.Schulenburg, R.Z.Liu 等修改,补正。算法对输入的灰度图像的直方图进行分析,将直方图分成两个部分,使得两部分之间的距离最大。划分点就是求得的阈值。都是老外写的,经典哦。-OTSU images calculated value of the two adaptive threshold, OTSU algorithm can be calculated adaptive threshold (for conversion to gray scale images binary images), a simple and efficient manner. The following code from the earliest to provide Ryan Dibble, after a more than Joerg.Schulenburg, R. Z. Liu amend the correction. Algorithm for the importation of gray-scale image histogram analysis of histogram is divided into two parts, Part 2 makes the distance between the largest. Demarcation point out the threshold. Foreigners are written in the classical oh. Platform: |

Description: 图像的二值化处理就是讲图像上的点的灰度置为0或255,也就是讲整个图像呈现出明显的黑白效果。即将256个亮度等级的灰度图像通过适当的阀值选取而获得仍然可以反映图像整体和局部特征的二值化图像。-Binary image processing is to say the point of image gray-scale home for 0 or 255, that is, speaking of the images clearly show the effect of black and white. Brightness is about 256 levels of gray-scale image through appropriate threshold can be selected to reflect the characteristics of the overall and partial image of the binary image. Platform: |

Description: 基于Mean Shift的图像分割过程就是首先利用Mean Shift算法对图像中的像素进行聚类,即把收敛到同一点的起始点归为一类,然后把这一类的标号赋给这些起始点,同时把包含像素点太少的类去掉。然后,采用阈值化分割的方法对图像进行二值化处理。-Mean Shift Based on the process of image segmentation is the first to use the image Mean Shift algorithm for clustering of pixels, that is, to converge to the same point as a starting point to the category and then assigned to this type of labeling of these starting points, at the same time to contain too few pixels to remove the category. Then, using thresholding segmentation method of binary image processing. Platform: |

Description: 程序可以选择输出二值图像。二值图像可以通过对每个梯度点取阈值得到,其中阈值T为输入参数。并且要求结合3*3掩模的平滑运算和本实验上面的原算,并对图像进行处理,分割出图像中间的大血管区域,并将结果用二值图表示。在实验中需要对平滑运算方法和阈值T进行反复调整。-Program can choose the output binary image. Binary image can be taken for each gradient point to the threshold should be, in which the threshold T for the input parameters. And requirements with 3* 3 mask and the smooth operation of the experiment above the original balance, and image processing, image segmentation of the middle region of the great vessels, and the results expressed by binary image. In the experiment the need for smooth computing methods and repeated T threshold adjustment. Platform: |

Description: This code demomstrates an improved algorithm based on the local binary fitting (LBF) model
in Chunming Li et al s paper:
"Minimization of Region-Scalable Fitting Energy for Image Segmentation",
IEEE Trans. Image Processing, vol. 17 (10), pp.1940-1949, 2008.
Usage: These codes can be used for Matlab 7.0.4 or higher versions in Windows.
Run the Demos in the M-files for several test images. Once an image comes out, click
the mouse to generate a polygon as the initial contour: left click to get
a number of points, then right click to get the end point.
The number of iterations may need to be increased if the initial contour is too far
away from the desired object boundary. -This code demomstrates an improved algorithm based on the local binary fitting (LBF) model
