Template-based watermarking method for depth-image-based rendering based 3D image and apparatus thereof

Abstract

Provided are a template-based watermarking method for a DIBR 3D image and an apparatus thereof. The method includes: determining a template watermark inserting area and a message watermark inserting area in spatial domain of an image; transforming the determined template watermark inserting area into a frequency domain to insert at least one preset template watermark and transforming the determined message watermark inserting area into a frequency domain to insert a preset message watermark; and transforming the template watermark inserting area, into which the template watermark is inserted, into a spatial domain and transforming the message watermark inserting area, into which the message watermark is inserted, into a spatial domain.
