摘要
目的:比较两种不同牙本质电镜照片预处理方法,探讨影像数字化预处理获取高质量牙本质显微结构的可行性。方法:采用分段线性增强和直方图均衡技术对牙本质电镜照片进行处理,比较两种方法对牙本质微结构图像的影响。结果:经过处理后的图像质量均明显改善,表现为图像对比度增加,牙本质微结构特征更加明显。其中直方图均衡化效果优于分段线性增强技术。结论:图像增强技术可明显改善牙本质电镜照片质量,可为研究牙本质的显微结构提供高质量的图像。
Objective：By comparing two different pre-processing methods,the feasibility of obtaining high quality of microstructure of dentin was thoroughly discussed.Method：Two digital image improving technics were applied in pre-processing step,namely median filter,histogram equalization,gray-scale linear transformation and edge enhancement.And the improvements were compared by histograms.Result：The quality of the images was greatly improved in both methods.The contrast was stretched and the details of dentin microstructure were sharpened.In addition,histogram equalization showed better results than gray-scale linear transformation.Conclusion：Higher quality image and more details of dentin microstructure can be obtained by pre-processing methods.
