Abstract

The invention provides a system and a method for subjective assessment of stereoscopic videos. The system comprises a server, a client side and a comprehensive assessment system, wherein the server is used for storing assessment task information and video sequences; the client side is used for acquiring the assessment task information in the server, acquiring a plurality of corresponding video sequences from the server according to the assessment task information, recording user information and playing current to-be-assessed video sequences according to user's choices so as to store assessment scores after the user completes assessment of the current to-be-assessed video sequences, and uploading the user's assessment score of each video sequence of the video sequences and the user information to the server; and the comprehensive assessment system connected with the server is used for making statistics on user number according to the user information and analyzing all the assessment scores according to the user number so as to obtain final assessment results. According to the embodiment, mutual interference among assessment staff is lowered, and assessment objectivity is guaranteed so that the assessment results are more authoritative and persuasive.

Description

technical field [0001] The invention relates to the technical field of video subjective evaluation, in particular to a stereoscopic video subjective evaluation system and method. Background technique [0002] Video subjective evaluation is a method of video quality evaluation through artificial means. This method uses statistical methods to analyze and process the evaluation results, and finally obtains convincing evaluation results. It plays a very important role in the field of video evaluation. Generally speaking, a complete video subjective evaluation system should have related functions such as evaluation result analysis and management, evaluation video management, etc. in addition to the evaluation system. [0003] Stereoscopic video, as a form of video representation, often uses video clips from multiple perspectives to better reflect the information of the scene. Since its display has changed from a single perspective to multiple perspectives, it also has a certain i...
