Embodiment approach 1

[0038] The invention discloses a light field editing propagation method, comprising the following steps:

[0039] S1: Input a light field image array and obtain the image depth of the light field image array. The light field image array is M*N images obtained by sampling the same object point at different viewpoints, where M>1, N>1, and both are positive integers. The light field image array can be the image array collected by an M*N camera array composed of multiple cameras, or a moving single camera can be used to separate It is obtained by collecting images from different viewpoints. The image depth of the light field image array can be obtained by shooting with a corresponding depth camera array, or the corresponding image depth can be calculated by using a currently relatively mature method for calculating a depth map.

[0040] S2: Obtain user-desired edits in the light field image array.

[0041] S3: Transform the light field image array into an epipolar plane image a...

Embodiment 2

[0059] The invention also discloses a light field editing propagation device, including:

[0060] The light field image array acquisition module is used to acquire the image depth of the light field image array module and the light field image array. The light field image array is M rows*N columns of images obtained by sampling different viewpoints on the same object point, wherein, M>1, N>1, and both are positive integers;

[0061] The user expects edit obtaining module, which is used to obtain the edit expected by the user;

[0062] The epipolar plane image array conversion module converts the light field image array into an epipolar plane image array. The epipolar plane image array is composed of several epipolar plane images, and each row of the epipolar plane image is the extracted light field The pixels of the same row in all viewpoint images in the same row of the image array are formed, or the columns of the epipolar plane image are composed of pixels in the same row ...

Abstract

The invention discloses a light field compilation transmission method and a related device. The method comprises the steps of: S1 inputting a light field image array, and obtaining the image depth of the light field image array; S2 obtaining compilation expected by a user; S3 converting the light field image array into an epipolar plane image array; S4 transmitting the compilation expected by the user to an area which is most similar to an original pixel of the position in which the compilation expected by the user is positioned on an epipolar plane image, so as to obtain a preliminary transmission result; S5 converting the preliminary transmission result into an original image domain; S6 performing fine compilation transmission on a single visual point in the original image domain. By using the light field compilation transmission method, the technical problems of poor compilation transmission effect and complex compilation transmission process are effectively solved.

Description

technical field [0001] The invention relates to the fields of computer vision technology and image processing, in particular to a method and device for light field editing and propagation. Background technique [0002] Image editing and dissemination methods are currently research hotspots in computer image processing, video processing and other disciplines, and are widely used in film and television production, animation production, interactive video and image processing and other fields. Image editing propagation propagates the editing effect expected by the user to the entire image, where the editing effect expected by the user includes features such as color, texture, and tone of the image. The editing propagation of images or videos is based on the similarity between the pixels or structures in the target area and the pixels or structures in the user-set area, and the user-defined editing effect is propagated to areas with high similarity according to certain criteria. ...
