Abstract
This paper used the random walker, a multiple structure semiautomatic segmentation approach, for rapid delineation of speech articulators in magnetic resonance imaging (MRI) images. Results on the delineation of the tongue and surrounding structures in both 2D and 3D are shown. Efficiency and sensitivity of the approach as well as other factors that may affect the results were assessed by analyzing the delineations of naive raters who used the program. The results of both naive raters and experts using the semi-automatic program were compared to expert manual delineations. Our results show that this semi-automatic approach is efficient, accurate, and easy to use.
