Abstract
This paper is to propose a method to obtain a new digital hologram content, a high value-added digital content, by manipulating one or more existing digital hologram contents or depth informations. For the depth informations, we use both the ones converted from disparities by stereo matching and the ones taken by time-of-flight (TOF) depth cameras. For them, we analyze the properties and their differences for the two kinds of depth informations and propose a conversion method to homogenize them. By using them, we propose a method to convert and synthesize the depth informations to calculate a new CGH. Also, we propose a method to get a new digital hologram content by synthesizing the digital holograms themselves according to their linearity. The proposed methods are experimented with various depth informations and digital holograms to show that they are very effective as the manipulating methods for digital hologram contents.
