A dynamic FFR scheme is developed where the optimal SINR threshold is determined using Otsu's method, a digital image processing technique. The optimal SINR threshold is calculated based on periodic SINR values in the cells, and β_FR then set proportionately to the number of users in each ...
Global image threshold using Otsu's method collapse all in pageSyntax T = graythresh(I) [T,EM] = graythresh(I)Description T = graythresh(I) computes a global threshold T from grayscale image I, using Otsu's method [1]. Otsu's method chooses a threshold that minimizes the intraclass vari...
摘要:最大类间方差(Otsu)图像分割法是常用的一种基于统计原理的图像阈值分割方法。为了改善Otsu耗 时较多、分割的精度低、易产生图像误分割等不足,将猴王遗传算法与Otsu算法结合,运用猴王遗传算法的原理,寻 找图像灰度的最大类间方差,即最佳阈值。结果表明,结合后的方法不仅提高了图像的分割质量、缩短了运算时 ...

Using this threshold value and the two mean values as calculated, this method separates the image into three classes instead of dividing into two classes as is done in the standard Otsu's method. The first class is the background and the second class is the foreground. The third class is ...

Threshold methodGenetic algorithmThreshold segmentation method was widely applied in image process and the selection of threshold affected the final results of image segmentation to a large extent. In order to improve the accuracy and the calculation speed of image segmentation, an Otsu threshold ...
It finally converts the threshold space to an angle space from 0掳 to 90掳, and the threshold search range is compressed to improve its efficiency. As the gesture is close to the background and the boundary is blurred, this paper combines the global and local Otsu's method to segment ...
