Problems solved by technology

This method requires the training of machine learning models for different types of scenes, and requires the collection of a large number of images as training data. The training process takes a long time (hours to days)
At rendering time, this method also takes considerable time (tens to hundreds of milliseconds) for model inference, and there is no guarantee that the model will always generate artifact-free images

Embodiment Construction

[0040] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0041] figure 1 It is a flow chart of the method for removing light field rendering artifacts according to the present invention, and the following will refer to figure 1 , the method for removing light field rendering artifacts of the present invention is described in detail.

[0042] First, in step 101, the parameterization of the grid representation of the scene is calculated, and a corresponding parameterized image is generated according to the light field source image and the parameterized grid.

[0043] Preferably, the step of generating a parameterized image can be specifically performed as follows: converting the fuzzy geometry of the scene into a grid repr...

Abstract

The invention discloses a light field rendering artifact removal method. The method comprises the following steps: generating a corresponding parameterized image according to a light field source image and a parameterized grid; marking an artifact area on the parameterized image; obtaining an artifact-free image corresponding to the parameterized image; fusing the parameterized image and the image without artifacts of the parameterized image; and modifying the light field source image based on the fused parameterized image. According to the light field rendering artifact removal method, the light field source image is modified to be matched with the scene geometry accurately, the artifact phenomenon in light field rendering is removed, and a more real rendering result is presented to a user; the processing time is shortened, and the model reasoning overhead during rendering is saved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional computer graphics, in particular to a method for removing light field rendering artifacts based on edge estimation. Background technique [0002] In the field of real-time rendering of 3D computer graphics, the light field rendering method can produce photo-realistic rendering results, and can represent scenes that are difficult to represent by other rendering methods such as anisotropic materials, participating media, and global illumination, and can utilize existing graphics hardware Its rasterization and texture mapping functions are widely used in the fields of film and television entertainment, cultural communication, cultural relics protection, and smart cities. [0003] Existing light field rendering methods can be divided into two categories, those that do not require geometry and those that require geometry. [0004] The light field rendering method that does not require geomet...
