Stereoscopic seam carving and scaling method in vertical direction

Abstract

The present invention discloses a stereoscopic seam carving and scaling method in the vertical direction. The method comprises the steps of A, inputting the left view, the right view and the disparity image of an original stereoscopic image, and setting the resolution of a target image; B, according to an energy function, calculating the energy value of each pixel point in the left view of the stereoscopic image; C, based on the dynamic programming method, finding out a plane seam in the left view of the stereoscopic image in the horizontal direction; D, executing the real projection strategy, and mapping the plane seam in the left view of the stereoscopic image into the right view of the stereoscopic image; E, according to an obtained seam section in the right view of the stereoscopic image through the real projection process, executing a policy based on the combination of the traditional seam carving method and the virtual projection method, spicing up spaced seams to obtain a corresponding seam in the right view of the stereoscopic image in the horizontal direction; F, simultaneously increasing or deleting the seam in the left view of the stereoscopic image and the seam in the right view of the stereoscopic image; G, repeatedly performing the steps C to F till the stereoscopic image is scaled to a specified size, and outputting a final left view and a final right view. According to the technical scheme of the invention, the overall features of the scaled image can be maintained, and important objects are highlighted. Meanwhile, the stereoscopic information of the stereoscopic image can be maintained.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a engraving and scaling method for three-dimensional joints in the vertical direction, which can be applied to the reduction and enlargement processing of the vertical direction of the three-dimensional image. Background technique [0002] With the promotion of stereoscopic display devices of different specifications, in order to meet the playback requirements of display screens with different aspect ratios, non-uniform scaling of stereoscopic images has attracted the attention of scholars at home and abroad. Traditional content-aware image scaling methods focus on the scaling of planar images. The research points include the accurate detection of salient areas, the avoidance of image distortion and fracture, the maintenance of main features and smoothness of the image, etc., which can be roughly divided into discrete and continuous scaling methods. Among them, the di...

Problems solved by technology

However, after being processed by this method, straight-line objects in the image tend to be bent, which brings uncomfortable viewing experience to users

At the same time, the sparse correspondence between size-invariant feature conversion depends on the scene structure of the image, and this method has limitations in application scenarios.

[0004] In summary, the existing content-aware stereoscopic image scaling methods have limitations in practical use, so it is necessary to improve
