Embodiment Construction

[0053] In order to make those skilled in the art understand better, below in conjunction with Table 1 and appendix figure 2 Explain the production of stereoscopic image resources in the specific implementation; at the same time combined with the attached image 3 , attached Figure 4 and Table 2 for further detailed introduction to the subjective evaluation test in this method.

[0054] Using this method to detect the comfort level of stereoscopic images, the process mainly includes five stages: stereoscopic image resource production, environment layout, practice demonstration, viewing and scoring, and data processing.

[0055] 1. Stereo image resource production

[0056] Firstly, four stereoscopic image features are selected: the disparity (depth) of the plane where the motion is located, the speed of motion, and the number and size of moving objects.

[0057] Set the final dynamic image size to 576×768pixels, and the foreground moving object to be a sphere. The value se...

Abstract

The invention discloses a three-dimensional image comfort level detecting method based on three-dimensional image features. The method concentrates on the relation between the parallax as well as the motion features of three-dimensional images and the comfort level of the three-dimensional images and comprises, firstly, obtaining the parallax and a plurality of motion-associated features of the images; secondly, establishing a comfort level model for representing the nonlinear relation between the features and the comfort level of the three-dimensional images through subjective experiments; lastly, according to the features of the three-dimensional images and the nonlinear comfort level model, performing comfort level estimation on the three-dimensional images objectively. The three-dimensional image comfort level detecting method based on the three-dimensional image features can help compute out the three-dimensional image comfort level according to a plurality of relatively intuitive image features and accordingly provide reference for estimation and making of three-dimensional images.

Description

technical field [0001] The invention belongs to the field of three-dimensional display evaluation, and in particular relates to a three-dimensional image comfort detection method based on the characteristics of the three-dimensional image. Background technique [0002] Although the application of stereoscopic display technology in fields such as television broadcasting, video game, meeting, medical treatment, education, commerce is more and more. However, due to technical and cost constraints, there are still many risks and hidden dangers in viewing stereoscopic displays, such as visual fatigue and image discomfort. These problems not only seriously affect user experience, but also restrict the development and popularization of stereoscopic display technology. Therefore, it is of great significance to improve the viewing experience of stereoscopic display by studying various influencing factors of stereoscopic display comfort, and then taking measures to prevent and allevia...
