论文摘要
在本文中，我们评估了头部运动对用户视力的影响及其对图像受损的质量感知。一个人可以感知的视觉信息量存在物理限制，并且可以探索我们的身体的速度以及我们的头部可以探索场景的速度。在这些局限性中，有基本解决方案用于多媒体系统的通信。因此，要求受试者评估电视屏幕处于动态（移动）状态时在电视屏幕上显示的静态图像的感知质量。这个想法可能适用于虚拟现实应用程序，因此，我们还测量了头部安装显示器上每个主题的图像质量感知。实验表明，当用户的头部不静态时，视力和质量感知的显着下降，并指出没有用户注意任何损害的情况下可以降低质量的程度。
In this paper we assess the impact of head movement on user's visual acuity and their quality perception of impaired images. There are physical limitations on the amount of visual information a person can perceive and physical limitations regarding the speed at which our body, and as a consequence our head, can explore a scene. In these limitations lie fundamental solutions for the communication of multimedia systems. As such, subjects were asked to evaluate the perceptual quality of static images presented on a TV screen while their head was in a dynamic (moving) state. The idea is potentially applicable to virtual reality applications and therefore, we also measured the image quality perception of each subject on a head mounted display. Experiments show the significant decrease in visual acuity and quality perception when the user's head is not static, and give an indication on how much the quality can be reduced without the user noticing any impairments.
