Laryngeal high-speed videoendoscopy is a state-of-the-art technique to examine physiological vibrational patterns of the vocal folds. With sampling rates of thousands of frames per second, high-speed videoendoscopy produces a large amount of data that is difficult to analyze subjectively. In order to visualize high-speed video in a straightforward and intuitive way, many methods have been proposed to condense the three-dimensional data into a few static images that preserve characteristics of the underlying vocal fold vibratory patterns. In this paper, we propose the "glottaltopogram," which is based on principal component analysis of changes over time in the brightness of each pixel in consecutive video images. This method reveals the overall synchronization of the vibrational patterns of the vocal folds over the entire laryngeal area. Experimental results showed that this method is effective in visualizing pathological and normal vocal fold vibratory patterns.

声门图：一种分析声带高速图像的方法。

喉部高速视频内窥镜检查是一种最先进的技术，用于检查声带的生理振动模式。高速视频内窥镜以每秒数千帧的采样率产生大量难以主观分析的数据。为了以直接和直观的方式可视化高速视频，已经提出了许多方法来将 3D 数据压缩成一些静态图像，这些图像保留了潜在声带振动模式的特征。在本文中，我们提出了“声门图”，它基于对连续视频图像中每个像素的亮度随时间变化的主成分分析。这种方法揭示了整个喉部区域声带振动模式的整体同步。
