| 摘 要： | Otsu自适应背景分离的局部直方图均衡化增强算法是综合改进后的Otsu自适应背景分离算法和局部直方图均衡化增强算法的一种新处理方法,首先,利用改进后的Otsu算法对图像进行目标区域和背景区域的分离,然后利用分离出来的目标区域进行直方图均衡化处理。实验结果表明,图像经过处理后,目标区域对比度明显增强。

| Abstract: | The presented algorithm is a novel method for the enhancement of medical image.For an input medical image,we use the improved algorithm of self-adaptive Otsu to separate the target area from background pixels,then the area of interested target is processed through local area histogram equalization method.The experimental results illustrate that the contrast ratio of the area for the target is enhanced greatly after the input image is processed by our algorithm,justify the power of the presented methodology. |
