摘要:
The present invention relates to a device and a method for estimating a depth map, and a method for making an intermediate image and a method for encoding multi-view video using the same. More particularly, the present invention relates to a device and a method for estimating a depth map that are capable of acquiring a depth map that reduces errors and complexity, and is resistant to external influence by dividing an area into segments on the basis of similarity, acquiring a segment-unit initial depth map by using a three-dimensional warping method and a self adaptation function to which an extended gradient map is reflected, and refining the initial depth map by performing a belief propagation method by the segment unit, and achieving smoother view conversion and improved encoding efficiency by generating an intermediate image with the depth map and utilizing the intermediate image for encoding a multi-view video, and a method for generating the intermediate image and a method for encoding the multi-view video using the same.
