Abstract: In order to suppress the noise due to chaotic scattering and improve the quality of the optical tomography image (OCT), we propose an improvement of our previous filter. The main idea of the new filter is based on the use of several images obtained by the OCT probing head from the same location on the skin surface. The efficiency of the multi-sample filtering algorithm is demonstrated on test examples and on real OCT images.
