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 object by adjusting the size and depth of the specific object, in order to Increase the three-dimensionality of the object

Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] An object-based stereo image depth adjustment method proposed by the present invention, its overall realization block diagram is as follows figure 1 As shown, it includes the following steps:

[0043] Step 1: Denote the left-viewpoint image, right-viewpoint image and left-disparity image of the stereoscopic image with a width of W and a height of H to be processed 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)}.

[0044] Step 2: Split {L(x,y)} into A non-overlapping quadrilatera...

Abstract

The invention discloses an object-based stereo image depth adjusting method. According to the method, by extracting the total edge preserving energy, the total object control energy, the total depth control energy and the total background preserving energy which correspond to a left-viewpoint image and a right-viewpoint image of a stereo image and conducting optimization to enable the total energyto be minimum, an optimal similarity transformation matrix is acquired, therefore, the stereo image obtained after depth adjusting can preserve the exact object shape and achieve the high comfort anddepth feeling, and the scaling of important content can be adaptively controlled according to the choice of a user; and deformation of quadrilateral meshes is controlled by controlling coordinate locations of all feature points in an important area and a background area in the stereo image, and then the comfort and the depth feeling of the stereo image obtained after depth adjusting can be guaranteed.

Description

technical field [0001] The invention relates to an image signal processing method, in particular to an object-based stereoscopic image depth adjustment method. Background technique [0002] With the rapid development of 3D technology, stereoscopic images and stereoscopic videos are getting more and more attention and love from people. Especially with the development of mobile phones, tablets and personal computers, the display of mobile terminals is becoming more and more popular among users. 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 object by adjusting the size and depth of the specific object, in order to Increases the three-dimensionality of the object. Therefore, when displaying stereoscopic images and stereoscopic videos on the screen of a mobile terminal, object-based depth adjustment can enhance the attention a...
