| 摘 要： | 介绍B超图像以及对其进行图像增强的原因。对直方图均衡化、对数直方图均衡化和排序直方图均衡化原理作介绍,从理论上分析这3种算法吞噬灰度值的原因。提出一种保留灰度级不变的改进直方图均衡化算法。使用直方图均衡化、对数直方图均衡化、排序直方图均衡化和该文提出的改进算法对B超体模图进行图像增强实验,结果表明该文提出的改进算法在B超图像上的增强效果比直方图均衡化、对数直方图均衡化和排序直方图均衡化算法要好。

| Abstract: | The ultrasound B-mode image and the image enhancement are introcued.The cause of amalgamation for histogram equalization,logarithm and order histogram equalization is analyzed theoretically.An improved histogram equalization method is proposed to maintain the gray level.The experimental results with dummy ultrasound B-mode images demonstrate that the image enhancement performance of the proposed method is better than those of histogram equalization,logarithm and order histogram equalization. |

| Keywords: | ultrasound B-mode image histogram equalization gray level image enhancement |
