RESUMO
In this work, different computational techiniques were used and evaluated for image stabilization of videolaringoscopy scenes, so that the unwanted movements coming from cameraman and patients moviments can be removed, thus improving their quality. After stabilizing the video, we can get a kymography, an examination which allows us to visualize the vibratory pattern of vocal fold, with a good quality. The techniques used were spatial correlation, phase correlation and Optical Flow.
