Paper Abstract

The application of non-linear anisotropic diffusion to reduce the speckle noise and enhance the structural boundaries in optical coherence tomography is presented. Non-linear diffusion maximally low-pass filters those parts of the image that correspond to speckle noise, while preserving information associated with structural boundaries. It is shown that this technique is efficient to enhance the quality of optical coherence tomogram, making the accurate image quantification possible.
