Title:
IMAGE DEPTH PREDICTION METHOD AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/193976
Kind Code:
A1
Abstract:
The present application relates to the technical field of image processing, and in particular to an image depth prediction method and an electronic device. The method comprises: acquiring a main view and a first auxiliary view, the main view comprising a first pixel, the first pixel corresponding to a second pixel at a first hypothetical depth, and the second pixel being located on the first auxiliary view; updating feature information of the second pixel according to the feature information of the second pixel and feature information of at least one third pixel; a fourth pixel being a pixel on the first auxiliary view corresponding to the first pixel at a second hypothetical depth; and obtaining a probability of the first hypothetical depth according to feature information of the first pixel and the updated feature information of the second pixel. In the method, features of pixels between adjacent sampling points can be aggregated into features of nearby sampling points, and accordingly, the possibility that a corresponding hypothetical depth is the real depth of a pixel of a main view is determined, so that the accuracy of depth prediction is improved.
