我们使用改进的压缩传感光学相干层析成像(MOCS-OCT)来研究降噪。结果表明，与经典平均方法相比，平均修正CS重建方法在信噪比、局部对比度和对比度噪声比(CNR)方面获得了更好的图像质量，同时减少了重建图像所需的总数据量。与具有相同欠采样数据量的基于标准CS的平均方法相比，情况也是如此。
We study noise reduction using Modified Compressive Sensing Optical Coherence Tomography (MoCS-OCT). We show that averaged Modified-CS reconstruction achieves better image quality in terms of SNR, local contrast, and contrast to noise ratio (CNR), compared to the classical averaging method while reducing the total amount of data required to reconstruct the images. The same is also true when compared with standard CS based averaging method with same amount of under-sampled data.
