Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] 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:

[0041] ①The left viewpoint image, right viewpoint image and left disparity image of the stereoscopic image with width W and height H to be processed are correspondingly recorded as {L(x,y)}, {R(x,y)} and {d L (x,y)}; among them, 1≤x≤W, 1≤y≤H, both W and H can be divisible by 8, L(x,y) means 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 The pixel value of the pixel whose coordinate position is (x, y) in (x, y)}.

[0042] ②Split {L(x,y)} into A non-overlapping quadrilateral gr...

Abstract

The invention discloses a stereo image repositioning method, including the following steps: extracting the image quality energy, the stereo quality energy and the important content energy corresponding to a left viewpoint image, performing optimization to ensure that the total energy corresponding to the left viewpoint image is minimized, and obtaining an optimal similarity transformation matrix and depth value set. Thereby, the obtained repositioned stereo image can better retain the important significant semantic information and maintain the visual comfort, and can adaptively control the scaling ratio of important contents according to the selection of users; and according to the method, a horizontal coordinate location, a vertical coordinate location and a depth value of the stereo image are simultaneously adjusted, so that the important significant information of the repositioned left viewpoint image can be retained, the phenomenon that the repositioned left viewpoint image matchesa repositioned right viewpoint image that is obtained from a repositioned left parallax image can also be ensured, and thus the comfort and depth of the repositioned stereo image can be ensured.

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 image size 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 changes in stereoscopic depth perception, and in severe cases, it will cause visual ...
