摘　　要：在图像工程中,图像增强方法有多种,如增强对比度和动态范围压缩等等,这类处理方法比较灵活方便,处理效果也不错,但对于某些灰度分布很密集或对比度很弱的图像,虽然也能起到一定的增强效果但并不明显。对于这种情况就可以采用灰度直方图变换方法将原始图像(细菌图片)密集的灰度分布变得比较稀疏,从而拉大图像的对比度并在视觉上达到明显增强的效果,使一些原本不易观察到的细节能变得清晰可辨。There are many image enhance methods in image engineering such as contrast enhancement and dynamic range compression.These methods are much agile and convenient,and the treatment efficiency is considerably good.yet which is very weak.for gray concentrated or contrast.Some enhance efficiency will be good with enhance effect being not obvious.Under this condition,using gray scale bargraph transformation process makes coarctate gray scale distribution of original image sparse,and non-easy observed details clear.
