Abstract: A patch based depth mapping method and apparatus for high-efficiency encoding/decoding of a plenoptic video is proposed. The method may be performed in an electronic apparatus to classify a reference image and an additional image from a plenoptic video during encoding the plenoptic video and then generate an atlas including a patch using the additional image. The method may include mapping a depth value by applying minimum-maximum linear scaling in units of an input viewpoint image. The method may also include finding a minimum value and a maximum value of the depth value per the patch and remapping the depth value through minimum-maximum linear scaling.
