Title:
IMAGE PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/123357
Kind Code:
A1
Abstract:
An image processing method and apparatus, which are applied to a decoder. The image processing method comprises: determining first position information of at least two planar regions of a multiplane image in a reference coordinate system; determining second position information of at least one light ray in the reference coordinate system; determining the coordinates, in the reference coordinate system, of at least one intersection point of the light ray and the at least two planar regions on the basis of the first position information and the second position information; and determining image information of at least one pixel point according to the coordinates of the at least one intersection point. The method can simplify the operation process of determining the coordinates of at least one intersection point of a light ray, which corresponds to a pixel point, and at least two planar regions, such that the complexity of a rendering process of the pixel point can be reduced.
