| 摘 要： | 在分析和比较全局性直方图均衡化和适应直方图均衡化增强胸透Ｘ光图象的基础上，采用快速适应直方图均衡化来进行图象处理，效果较为理想。引外，利用帧平均法和傅里叶阻滤波法对图象处理中产生的图象噪声进行了消噪声声处理，提高了原胸透Ｘ光图象的质量。

| Abstract: | In this paper, the applications of global histogram equalization and adaptive histogram equalization used in the enhancement of the chest X ray contrast are discussed, and the merits and shortage of the two methods are compared, too. A fast adaptive histogram equalization method is presented to enhance X ray images. By analyzing the noise caused by enhancing the image, we use both frame average and band stop filter methods to eliminate the noise. The image processing result is satisfactory. |
