摘　　要：目的:解决传统的二维锐化增强算子不能很好解决扫描医用胶片图像不同区域不同模糊程度的问题。材料和方法:本文根据扫描仪成像系统的特点,提出了一维滤波进行处理。通过不同区域不同长度滤波算子的处理,保证了处理后的图像整体一致清晰。结果:本方法跟二维滤波相比运算量大幅下降,满足大尺寸扫描图像实时处理的要求。结论:试验结果表明,该一维算子稳健高效,提高了图像的清晰度、对比度,让医生能够更准确的诊断。Objective： To solve the problem that the two sides of digital images through scanning films are blurred and traditional two dimensions enhancement methods can＇t process it very well. Material and Methods： This paper presents one dimension filter operators based on scanner system. The new method that process different regains by different length filters can ensure that all the parts of processed image are almost same clear. Results： The proposed method is also a real-time method and much less calculation than traditional methods. Conclusion： Some experimental results applied to scan images verify the effectiveness of the proposed technique.
