【摘要】 针对粒子场全息图像亮度不均匀产生的原因进行理论分析 ,采用同态滤波图像增强方法对微粒场全息图像亮度不均匀进行校正 ,消除了对图像处理中的二值化处理结果带来的影响 ,提高了原图像的象质 ,为进一步提取图像中的特征信息打下了良好的基础 通过计算机模拟分析和验证 ,证实了同态滤波图像增强方法是有效的预处理方法更多还原

【Abstract】 The application of homeostasis filtering in image process of particles field holography was discussed. Holographic reconstructed image with uneven brightness cannot be half toned effectively.How the uneven brightness creates was analyzed theoretically, and Homeostasis Filtering was used to adjust the uneven brightness. According to the computer simulation and experiment, it was proved that homeostasis filtering was an efficient method for adjusting uneven brightness before halftone process.更多还原
