On packing laser scanning microscopy images by reversible watermarking: A case study

Pairs of images of the same fleld-of-view collected by two complementary Laser Scanning Microscopy (LSM) work-modes are packed together by embedding one image of the pair into the other by reversible watermarking. One image remains visible and the other can be easily extracted at no extra transmission bandwidth cost. The packing keeps together the data without any risk of confusion. The use of reversible watermarking ensures, if necessary, the recovery of the host at zero distortion. Experimental results for Confocal Laser Scanning Microscopy (CLSM) and Transmission Laser Scanning Microscopy (TLSM) image pairs are provided.
