We report on the quality assessment of an optical coherence tomography (OCT) image. A set of recent digital filters are used for denoising the interferometric signals. It is found that when a combination of continuous wavelet transform (WT) decomposition and the WT denoising techniques is imposed on raw signals, the highest signal-to-noise ratio of 17.8 can be reached. The structural similarity (SSIM) index is eventually employed to evaluate the modality of the reconstructed OCT image. Further, we found out that a SSIM value of about 0.95 can be reached, independent of the method used for envelope extraction.

利用小波变换技术增强的光学相干断层图像的结构相似性评估

我们报告光学相干断层扫描（OCT）图像的质量评估。一组最新的数字滤波器用于对干涉信号进行消噪。发现将连续小波变换（WT）分解和WT去噪技术结合使用于原始信号时，可以达到17.8的最高信噪比。最终采用结构相似性（SSIM）索引来评估重建的OCT图像的模态。此外，我们发现，与用于包络提取的方法无关，可以达到约0.95的SSIM值。
