Title:
METHOD AND APPARATUS FOR EXTRACTING DEPTH INFORMATION FROM IMAGE
Document Type and Number:
WIPO Patent Application WO/2016/006901
Kind Code:
A1
Abstract:
A method for extracting depth information from an image comprises the steps of: extracting a first patch data including data of each of a plurality of pixels corresponding to a predetermined region on the basis of a certain pixel position of a first image; receiving an input of the first patch data in a raster scan order; processing the first patch data that are input in the raster scan order using one-dimensional horizontal point spread function (PSF) and a plurality of filters, to which the one-dimensional horizontal PSF is applied, in order to generate a plurality of blurred patches; extracting second patch data which corresponds to the first patch data and includes data of each of a plurality of pixels corresponding to the predetermined region on the basis of a certain pixel position of a second image which is distinctive from the first image; comparing similarities between the second patch data and each of the plurality of blurred patches; and determining the depth of the certain pixel position on the basis of the comparison result.
