Abstract

Edge enhancement is fundamental in image processing for recognizing or highlighting image features. Existing methods can only function in free space or transparent media. It remains challenging to achieve edge enhancement in the presence of multiple scattering. In this work, we present an implementation of digital optical phase conjugation to achieve effective edge enhancement through scattering media. The hypothesis is verified through experiments; the performance is promising and can be tuned by adjusting the beam ratio. The method may potentially enrich the interpretation of images obtained from complex environments.
