Depth Estimation Using Normalized Displacement of Image Pairs

摘要

Systems and methods are provided for depth map estimation using normalized displacement of image pairs. In one embodiment, an image manipulation application identifies image pairs from an input image. Each of the image pairs includes an image portion from a first perspective and the image portion from a second perspective. The image manipulation generates displacement vectors for the image pairs. Each of the displacement vectors represents at least one of a horizontal displacement and a vertical displacement of the image portion from the first perspective to the second perspective. The image manipulation application generates normalized displacement vectors corresponding to the displacement vectors. Each of the normalized displacement vectors is generated by transforming a respective orientation of a corresponding one of the displacement vectors to a common reference direction. The image manipulation application generates a depth map based on the normalized displacement vectors.
