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 ...
(PSO) algorithm is easy to trap to local minima,the algorithm is sometimes inaccurate and instable when it is used in searching the best solutions of a function.To solve the problem,based on the Otsu segmentation method,the Otsu dual-threshold value method based on the parallel particle swarm...
Based on the study of image segmentation algorithm, this paper presents one kind of improved image segmentation algorithm by comprehensive using the Otsu method and the method based on fuzzy theory seeking image segment threshold. The method uses Otsu method, obtained by pre-segmentation threshold val...

In this paper, an adaptive edge detection method (Canny operator and Otsu threshold selection based adaptive edge detection method - COAED) is proposed. The COAED method combines a new hybrid filter with Canny operator to avoid the conflict of Canny operator between noise removing and edge locati...

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 ...
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 ...
