Method for determining number of stereoscopic image subjective assessment testees and experiment data

The invention discloses a method for determining the number of stereoscopic image subjective assessment testees and experiment data, and relates to the field of stereoscopic image quality subjective assessment. The method comprises the following steps of through analyzing preprocessing data, determining the number of the subjective assessment testees by perverting a confidence interval formula to shorten an experiment cycle and reduce the cost; performing a subjective assessment experiment by utilizing the determined reasonable number of qualified testees, including the processes of establishing a stereoscopic image database, selecting reasonable testing environmental conditions, selecting the testees according to standards and training and testing the testees; lastly, according to the image quality subjective assessment standard regulation and the Grubbs' test method, eliminating abnormal testees and reasonably screening abnormal data in experiment data to avoid the influence of the testees, the experiment environment and other uncertain factors on the accuracy of an experiment result. The method is based on stereoscopic image quality subjective assessment, and the accuracy of the experiment data result is improved from the angle of statistics.
