Embodiment Construction

[0028] In order to make the technical solution of the present invention clearer, the specific implementation manners of the present invention will be further described below.

[0029] 1. Stereo image parallax calculation

[0030] For stereo image pair I s , first apply the optical flow method to calculate its disparity map D.

[0031] 2. Preliminary position determination of stereoscopic subtitles

[0032] The present invention has the explanation of the following points: 1, for the stereoscopic image, the present invention selects two areas (upper area and lower area) as the candidate area that subtitle adds, as figure 1 As shown (the range of the upper area is Where W and H represent the width and height of the image respectively, and the range of the lower area is 2. Considering that the stereoscopic subtitles are often located outside the viewing screen, the subtitles in the present invention only consider adding the subtitles outside the screen (i.e. closer to the e...

Abstract

The invention relates to a stereoscopic caption adding method based on viewing comfort, which comprises the following steps of: (1) carrying out stereoscopic image parallax calculation; (2) carrying out stereoscopic caption initial position determination; (3) carrying out optimal caption position and parallax selection, i.e., in consideration of a case that the smaller a parallax value is, the easier viewing discomfort is to cause, carrying out sorting from big to small on a parallax data set P, selecting a small value with a high frequency as a final parallax value df when a stereoscopic caption is added, wherein such parallax value condition possibly can correspond to a plurality of candidate regions, and assuming that coordinates corresponding to the regions form a set Q, a final coordinate position (x, y) of the stereoscopic caption can be determined by selecting a coordinate position with the shortest distance from a coordinate point (X0, Y0) from the set.

Description

technical field [0001] The invention belongs to the field of image processing and relates to the problem of automatically selecting the position of stereoscopic subtitles to improve viewing comfort. Background technique [0002] With the rapid development of electronic technology and network technology, digital images are widely used in people's daily life. Stereoscopic images have developed rapidly in recent years, and have been successfully applied to various fields such as advertisements, television, dramas, and movies, and are closely related to people's lives. As a tool to assist image content, subtitles are crucial to human understanding of image information. At this stage, image subtitles mainly rely on manual addition in the later stage. This method is time-consuming and labor-intensive, which is not conducive to the rapid development of the field of three-dimensional information. Moreover, adding subtitles based on experience often results in occlusion of subtitle...
