Embodiment Construction

[0059] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0060] A kind of stereoscopic image repositioning method that the present invention proposes, its overall realization block diagram is as follows figure 1 As shown, it includes the following steps:

[0061] ①Record the left viewpoint image of the stereo image to be processed as {L i (x,y)}, the right viewpoint image of the stereo image to be processed is recorded as {R i (x,y)}, record the left disparity map of the stereo image to be processed as {d L (x,y)}, wherein, i=1,2,3, 1≤x≤W, 1≤y≤H, W represents the width of the stereoscopic image to be processed, H represents the height of the stereoscopic image to be processed, L i (x,y) means {L i The color value of the i-th component of the pixel whose coordinate position is (x, y) in (x, y)}, R i (x,y) means {R i The color value of the i-th component of the pixel whose coordinate position is...

Abstract

The invention discloses a three-dimensional image relocation method. The three-dimensional image relocation method comprises the steps that first, a three-dimension saliency map and a saliency energy map of a left viewpoint image are extracted, and a dynamic planning method is used for finding out all vertical gaps of the left viewpoint image; then all the vertical gaps of the left viewpoint image are adjusted according to the horizontal deviation values of all pixel points in the left viewpoint image, and all the optimal vertical gaps are acquired; afterwards, all the optical vertical gaps of a right viewpoint image are found out according to all the optimal vertical gaps of the left viewpoint image; the pixel points falling into all the optimal vertical gaps in the left viewpoint image and all the optimal vertical gaps in the right viewpoint image are removed, and the relocated three-dimensional image is obtained. The three-dimensional image relocation method has the advantages that important saliency semantic information is kept in the relocated three-dimensional image, and the consistency of the left viewpoint image and the right viewpoint image is also guaranteed.

Description

technical field [0001] The invention relates to an image signal processing method, in particular to a stereoscopic image repositioning method. Background technique [0002] With the rapid development of stereoscopic display technology, a variety of terminal devices with different stereoscopic display functions have also appeared widely. However, due to the wide variety of stereoscopic display To display on different stereoscopic display terminals, the size of the image must be adjusted first to achieve the effect of stereoscopic display. Traditional image scaling methods are by cropping or scaling by a fixed ratio, which may reduce the content of the image or cause significant object deformation. [0003] For stereoscopic images, stretching or shrinking along the horizontal or vertical direction will seriously affect the stereoscopic effect, resulting in changes in binocular parallax, resulting in depth distortion, and in severe cases will lead to the loss of stereoscopic e...
