摘要

为了提高SF

压力表盘图像分割准确度

对比了传统二维Otsu和Otsu双阈值分割算法

给出了一种改进二维Otsu算法。针对二维Otsu算法选取最佳阈值时存在的缺陷

提高了目标图像的阈值分割效果。实验结果表明:所提算法不仅满足对SF

压力表盘图像进行目标区域分割

同时具有更高的稳定性、快速性和分割精度。

Abstract

To enhance the image segmentation accuracy of SF

pressure dial

an improved two-dimensional Otsu algorithm is given through comparing two threshold segmentation algorithms such as traditional two-dimensional Otsu and Otsu double threshold. Aiming at the existing defect of optimal threshold selecting by two-dimensional Otsu algorithm

the overall threshold is redistinguished and combined with the square sum of deviations which is regarded as the fitness function

which can select the best threshold value to boost threshold segmentation effect of the target image. The experimental results show that the proposed algorithm not only meets segmenting the target area on the SF

pressure dial image

but also has higher stability

rapidity an

d segmentation precision.
