摘要

This paper presents a method to automatically segment tympanic membranes (TMs) from video-otoscopic images based on the deep learning approach. The paper introduces a hybrid loss function combining the Dice loss and active contour loss to the fully convolutional network. By this way, the proposed model takes into account the Dice similarity and the desired boundary contour information including the contour length as well as regions inside and outside the contour during learning. The proposed loss function is then applied to the fully convolutional network for tympanic membrane segmentation. We evaluate the proposed approach on TMs data set which includes 1139 otoscopic images from patients diagnosed with and without otitis media. Experimental results show that the proposed deep learning model achieves an average Dice similarity coefficient of 0.895, a mean Hausdorff distance of 19.189, and average perpendicular distance of 6.429, that outperforms other state-of-the-art methods.
