Description: Otsu方法是一种全局化的动态二值化方法,又叫大津法,是一种灰度图像二值化的常用算法。该算法的基本思想是:设使用某一个阈值将灰度图像根据灰度大小,分成目标部分和背景部分两类,在这两类的类内方差最小和类间方差最大的时候,得到的阈值是最优的二值化阈值。-Otsu method is a globally-oriented dynamic binary method, also known Otsu is a gray image binarization commonly used algorithms. The basic idea of the algorithm is: set a threshold value using a grayscale image based on the size of the gray, and the background section is divided into two types of target portion, between these two classes in the minimum variance and the variance of the largest class, I get the threshold is optimal binary threshold value.

Description: 大律法(OTSU)灰度图像阈值提取算法(C语言实现)。文件中已经有已经编译好的可执行文件,可以批量把灰度图片转化成二值化的二进制图像文件,可用于LCD显示屏视频动画的开发(例如Badapple)。
阀值是图像二值化处理中非常重要的一个参数,意思就是:如果灰度图像的像素颜色值大于该阀值就把该点当作黑色,小于该阀值就把改点当作白色。最简单的做法就是把阀值取为127(255的一半),但是这种做法是不科学的,处理后的二值化图像效果也很不理想。关于阀值的选取是一门很深的学问,有很多经典的算法用于选取该阀值,理论我就不做过多描述了,感兴趣的自己趣网络上搜索相关资料,我这里采用的是比较经典的大律法(OTSU)。-Large law (OTSU) threshold grayscale image extraction algorithm (C language). File has been compiled executable file, you can bulk of the gray image is converted to binary binary image file that can be used for the LCD display video animation development (for example Badapple).
Image binarization threshold is a very important process parameters, means: If the pixel color values gray image is larger than the threshold to put the point as a black, less than the threshold put the change point as white. The easiest way is to take the threshold of 127 (255 in half), but this approach is unscientific, binary image post-processing effects also far ideal. Select on the threshold of a very deep knowledge, there are many classical algorithms for selecting the threshold theory I do not do too much description, and search for relevant information of interest to their own interest on the network, I used here It is more classic big law (OTSU).

Description: 最大类间方差法是由日本学者大津(Nobuyuki Otsu)于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。它是按图像的灰度特性,将图像分成背景和目标2部分。背景和目标之间的类间方差越大,说明构成图像的2部分的差别越大,当部分目标错分为背景或部分背景错分为目标都会导致2部分差别变小。因此,使类间方差最大的分割意味着错分概率最小。(The largest between-class variance method was proposed by the Japanese scholar Nobuyuki Otsu in 1979. It is an adaptive threshold determination method, also known as the Otsu method, or OTSU for short. It is based on the grayscale characteristics of the image and divides the image into two parts: the background and the target. The larger the variance between the background and the target, the greater the difference between the two parts that make up the image. When the part of the target is wrongly divided into backgrounds or part of the background is mis-divided into goals, the difference between the two parts will be smaller. Therefore, the segmentation that maximizes the variance between classes means that the probability of wrong division is the smallest.) Platform: |
