摘要
由于共焦针孔的加入及现有太赫兹激光器输出不稳定,太赫兹共焦扫描显微成像所得图像的质量不高,将双边滤波算法应用于透射式太赫兹共焦扫描显微成像图像去噪复原,通过研究确定了适合于该情况的双边滤波参数,并且与中值滤波、均值滤波和开运算滤波的滤波性能进行比较,证明了双边滤波算法应用于透射式太赫兹共焦扫描显微成像图像去噪复原的可行性。
Abstract
Due to the addition of confocal pinholes and the unstable output of terahertz laser currently, the performance of terahertz confocal scanning microscopic imaging is not high. The bilateral filtering algorithm is applied to the image denoising of transmission type terahertz confocal scanning microscopic imaging. Through the experiment, the bilateral filtering parameters are calculated to fit this situation. Moreover, through the comparison of the filtering performance with median filtering, average filtering and open operation filtering, it is proved that the bilateral filtering algorithm is feasible to apply for image denoising of transmission type terahertz confocal scanning microscopic imaging.
