In this study, we developed a multi-view multiplexing algorithm based on the nearest point repeat (ICP) algorithm to reconstruct the missing information. The use of a biaxial angle stage allows for multi-view images to be obtained at varying degrees of control. The result of our proposed method is that it is possible to improve the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of dental OCT images. |
