Problems solved by technology

However, when stereoscopic images and stereoscopic videos are displayed on mobile screens, the stereoscopic effect will be weakened or even disappeared. Filmmakers try to make the viewer focus on the specific object by adjusting the size and depth of the specific object. to enhance the three-dimensionality of that particular object

Embodiment Construction

[0065] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0066] A three-dimensional image zooming method proposed by the present invention, the overall implementation block diagram is as follows figure 1 shown, it includes the following steps:

[0067] Step 1: The left view point image, the right view point image and the left disparity image of the stereo image whose width is W and height is H to be processed are correspondingly recorded as {L(x,y)}, {R(x,y)} and {d L (x,y)}; where both W and H are divisible by 2, 1≤x≤W, 1≤y≤H, L(x,y) indicates that the coordinate position in {L(x,y)} is ( The pixel value of the pixel point of x,y), {R(x,y)} represents the pixel value of the pixel point whose coordinate position is (x,y) in {R(x,y)}, d L (x,y) means {d L (x,y)} The pixel value of the pixel whose coordinate position is (x,y).

[0068] Step 2: Use the existing SIFT-Flow method to establish a mat...

Abstract

The invention discloses a stereo image zooming method, which extracts the coordinate offset energy of the target quadrilateral grids corresponding to all quadrilateral grids corresponding to all quadrilateral grids in the left and right viewpoint images that fall within the object selected by the user and the boundary of the object selected by the user , the background retention energy of the target quadrilateral grid corresponding to all quadrilateral grids falling in the background area, the size control energy and left-right consistency energy of the target quadrilateral grid corresponding to all quadrilateral grids falling within the object selected by the user, And through optimization, the total energy is minimized, and then the optimal target quadrilateral grid corresponding to each quadrilateral grid in the left and right viewpoint images is obtained, and according to the affine transformation matrix of each optimal target quadrilateral grid, the zoomed The advantage is that the zoomed stereoscopic image retains the precise object shape and accurate target focus depth, has a sense of immersion in close-up viewing, has a higher sense of depth, and can obtain a higher quality of three-dimensional experience.

Description

technical field [0001] The present invention relates to an image signal processing method, in particular to a stereoscopic image zooming method. Background technique [0002] With the rapid development of 3D technology, stereoscopic images and stereoscopic videos have attracted more and more people's attention and love. Especially with the development of mobile phones, tablets and personal computers, displays on mobile terminals are becoming more and more popular among users. However, when stereoscopic images and stereoscopic videos are displayed on the mobile screen, the stereoscopic effect will be weakened or even disappeared. The filmmakers try to make the viewer focus on the specific object by adjusting the size and depth of the object. to enhance the three-dimensionality of that particular object. Therefore, when displaying stereoscopic images and stereoscopic videos on the mobile screen, adjusting the focus depth of the camera can enhance the attention and depth of t...
