Laryngeal videostroboscopic image processing and its application in art phonetics

摘要

The objective measurement of vocal cords for function and morphology analysis is one of the goals of current vocalization research, especially in the field of art phonetics. The main purpose of our research is to analyze individualvideostroboscopic images quantitatively, and to provide helpful data for doctors to assist their clinical diagnosis and basic research. In this paper, we introduce the whole hardware devices first. Then we describe several algorithms that maybe useful for detecting the edge of vocal cords in an image. Finally, we put the system into practice to figure out the value of some important features of a clinically obtained real image.
