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: |

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: 图像分割指把图像分成各具特性的区域并提取出感兴趣目标的技术和过程，它是由图像处理到图像分析的关键步骤。小麦的图像分割是使用各种图像分割算法对小麦图像进行处理和研究，提取出有用的图像信息以实现小麦粘连籽粒的分离，为进一步利用图像处理技术分析小麦品质提供依据。因此，对小麦图像分割方法的研究具有十分重要的意义。
本文首先研究了图像分割算法的分类以及常用图像分割算法的基本原理。然后针对小麦图像的特点，研究了在不同光照、背景和连接情况下使用的小麦图像分割方法，对各种分割算法进行了比较、结合和改进。重点研究了基于小波变换的分水岭算法和阈值分割算法在小麦图像分割中的应用，并借助MATLAB工具软件对选定图像进行处理，实现了对小麦粘连籽粒的分离。最后本文对图像分割技术进行了展望。
本论文的研究对于图像分割技术在小麦品质中的应用具有一定的参考价值。
-Image segmentation is a technology and process that divide image into different character area, which is interesting us. It is a key step from image processing to image analyzing. The wheat image segmentation is a way using many algorithms does some research and processing, and it also can realize the separation of wheat adhesion and realize the extraction of useful image information. So it can lay the foundation for using image processing technologies to analysis the quality of the wheat. there is a very important meaning for the research of the image segmentation method.
This paper studies the class and the principle of segmentation algorithm in common use firstly, then, studies the wheat image segment algorithm with different illumination background. It contrasts kinds of algorithms, and improved them. This paper is based on wavelet transform, and combines with the watershed algorithm and the threshold segmentation method. Using the MATLAB software, does some process on the wheat i Platform: |

Description: Binary erosion and dilation, with fast iterative calls.
For any structuring element other than square or disk this function is way faster than imerode.m and imdilate.m (more than an order of magnitude). It s also handy when you don t have the Matlab Image Processing Toolbox :-)...
It also allows very fast iterative calls (for instance when sweeping the structuring element while looking for a certain effect, threshold in image statistics, etc).
See the help in bmorph.m and the attached .pdf file.-Binary erosion and dilation, with fast iterative calls.
