Abstract:
1. A method for generating a depth map implemented by at least one processing element, the method comprising: extracting the ground of a video image, wherein the ground has image characteristic distinguished from an object of the video image; classifying the video image as a long shot image or a non-long shot image based on a distribution value of the extracted ground; analyzing the video image and performing object detection in consideration of a distribution value of the extracted ground and a distribution value of a ground at the end of the video image when the video image corresponds to the non-long shot image; calculating a depth value gradually varied along a predetermined direction of the extracted ground when the video image corresponds to the long shot image and calculating depth value based on the object as a result of the object detection when the video image corresponds to the non-long shot image; and generating the depth map based on the depth value.
