Abstract:

Optical coherence tomography (OCT) is a new non-contact imaging method for medical diagnosis,with micron-resolution.This paper mainly uses Lucy-Richardson iterative principle and the method of image deconvolution based on Gaussian point spread function to recover the defocused spatial image that contains depth information,then we use image enhancement method based on the modified histogram equalization algorithm to increase the interval of the gray value of both depth information and speckle noise,separating useful information from speckle noise,which increases the image resolution.The processing results show that the proposed image processing method can improve the image longitudinal resolution and recover the deeper information of image.

Key words: Lucy-Richardson iterative;deconvolution;histogram equalization
