End-to-End Paired Ambisonic-Binaural Audio Rendering

IEEE/CAA Journal of Automatica Sinica 2024年第2期11卷 502-513页

Binaural rendering is of great interest to virtual reality and immersive media. Although humans can naturally use their two ears to perceive the spatial information contained in sounds, it is a challenging task for machines to achieve binaural rendering since the description of a sound field often requires multiple channels and even the metadata of the sound sources. In addition, the perceived sound varies from person to person even in the same sound field. Previous methods generally rely on individual-dependent head-related transferred function(HRTF)datasets and optimization algorithms that act on HRTFs. In practical applications, there are two major drawbacks to existing methods. The first is a high personalization cost, as traditional methods achieve personalized needs by measuring HRTFs. The second is insufficient accuracy because the optimization goal of traditional methods is to retain another part of information that is more important in perception at the cost of discarding a part of the information. Therefore, it is desirable to develop novel techniques to achieve personalization and accuracy at a low cost. To this end, we focus on the binaural rendering of ambisonic and propose 1) channel-shared encoder and channel-compared attention integrated into neural networks and 2) a loss function quantifying interaural level differences to deal with spatial information. To verify the proposed method, we collect and release the first paired ambisonic-binaural dataset and introduce three metrics to evaluate the content information and spatial information accuracy of the end-to-end methods. Extensive experimental results on the collected dataset demonstrate the superior performance of the proposed method and the shortcomings of previous methods.

选用Harris角点作为跟踪对象,将尺度空间引入角点检测,提取特征尺度上的Harris角点,并进行曲率非极大值抑制,滤除"伪角点",提高角点检测对尺度变化的抗扰能力.跟踪算法选用结合图像金字塔的光流法,迭代计算光流,并提出基于光流误差的跟踪算法,即用不同时间流的运动轨迹在同一帧图像的误差来衡量运动跟踪情况,避免跟踪点因被遮挡、消失或者纹理特征发生变化而导致跟踪失败.通过对不同视频图像进行检测的结果证明基于改进的角点提取和图像金字塔的光流法具有良好的跟踪效果,引入光流误差可以有效地滤除跟踪失败的特征点,准确估计运动目标的位置.
