Abstract

Abstract: A VR video comfort evaluation model based on motion perception is proposed for viewers who will feel discomfort such as vertigo and nausea after a virtual reality (VR) experience. By performing dense optical flow estimation on stereoscopic VR video and calculating the video frame velocity matrix by analyzing the horizontal and vertical motions in the scene, the frame acceleration feature extraction methods based on frame difference method and based on time domain are proposed. Taking the extracted velocity, acceleration and other motions features as input, a model is established using the support vector regression algorithm, and VR video experience comfort could be evaluated. The experiment shows that our model performs better than other models for introducing time-domain frame acceleration, and the results are closer to subjective evaluation values. The root mean square error (RMSE) is reduced to 7.0, and the Pearson linear correlation coefficient (PLCC) is increased to 0.955 3.
