Abstract
In this paper, two novel hologram image processing issues, i.e., hologram decomposition and hologram inpainting, are briefly reviewed and discussed. By hologram decomposition, one hologram can be decomposed into several subholograms and each sub-hologram represents one individual item in the 3D object scene. A Virtual Diffraction Plane based hologram decomposition scheme is proposed based on Otsu thresholding segmentation, morphological dilation and sequential scan labelling. Hologram decomposition can be employed for focus distance detection in blind hologram reconstruction. By hologram impainting, a damaged hologram can be restored by filling in the missing pixels. An exemplar and search based technique is applied for hologram inpainting with enhanced computing speed by Artificial Bee Colony algorithm. Potential applications of hologram inpainting are discussed.
