摘要

This paper reports a combined speckle and polarization-difference approach for imaging absorbing inhomogeneities embedded in optical scattering medium. Mathematical morphological operation has been used to suppress the speckle coarse grains and reconstruct the position of the absorbing inhomogeneities embedded in turbid medium. Moreover, we quantify the scattering coefficient of the background medium using the average granulometric size. Then the local speckle contrast ratio is applied to enhance the edges of absorbing objects.
