Embodiment Construction

[0035] The following description focuses on embodiments applicable to edge detection in light field images.

[0036] One idea is to provide a method of removing an object obscuring the background in a captured light field image and presenting a new image with the object removed, and wherein the pixels of the removed object can be obtained from the light field image with replaced by real background data from behind the object.

[0037] For easy understanding of the present invention, Figures 4a to 4c It is intended to illustrate the basis of the invention.

[0038] Figure 4 illustrates the optical setup of a simple camera comprising a main convex lens 41, and how light rays travel from a point from an object r, and the object s at least partially blocks the light path from this point of the object r. according to Figure 4a , it can be observed that the light path of an object s that obscures a point of another object still allows some rays from that point of object r to pa...

Abstract

A method and graphical user interface for manipulating objects in light field data are provided. The method and graphical user interface may be used to remove an object or obstacle blocking another object or the background in a captured scene. The method and graphical user interface can also be used for high precision edge detection in light field images.

Description

technical field [0001] The present invention relates generally to the field of light field imaging. More specifically, the present invention relates to a method, a graphical user interface and a computer program product for processing light field images. Background technique [0002] Light field imaging involves images created using light field photography, in which light field data (ie, angular information, position, and luminosity of light from the photographed object or scene) can be obtained from the resulting light field image. [0003] A standard 2D camera shoots rays in two dimensions at plane f. Luminosity and position are recorded as pixel value and pixel position (coordinates x and y). However, the angle of the light rays is not recorded. [0004] However, light field cameras record angular information and record luminosity and position. With the data describing the rays as vectors, the rendering of this image can be handled in ways that standard 2D cameras can...
