摘要
The present invention relates to a method for extracting factors for a content or context of a video (hereinafter situational factors) affecting on the safety of a viewer in watching a stereo three-dimensional (3D) video, the method comprises: (a) receiving a 3D video composed of a series of sections in time and context categories for the section, wherein the context categories are formed by classifying the sections of the 3D video into categories, respectively; (b) calculating the degree of variation of each section; (c) receiving the number of viewers (hereinafter push number) who express inconveniences among viewers who watched the 3D video, wherein a series of push numbers in time are received; (d) detecting, from the context categories, context categories in which the proportional coefficient of the degree of variation and the push number in the sections that fall into the context categories exceeds a reference range; (e) extracting the detected context categories as the situational factors. Thus, the method can extract factors such as details, features, or contexts of content causing the inconvenience of the viewer among factors causing inconvenience in using stereo 3D content, thereby providing factors capable of proposing a content production guideline for the stability of the viewer in watching 3D video.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) Start; (BB) End; (S10) Receive a 3D image, and a context category of each image section; (S20) Receive an inconvenience push number from a viewer; (S30) Calculate the degree of variation of each section in the 3D image; (S40) Determine whether the proportional coefficient of the degree of variation of a context category image and the push number exceeds a reference range; (S50) Extract the detected context categories as situational factors
