摘要:

Segmenting the tongue body is an essential step for automated tongue diagnosis, which is a challenge task due to the tongue body’s specificity and heterogeneity. The current deep-learning based tongue image segmentation networks are bloated with high computational complexity. In this study, a light-weight segmentation network for tongue images is proposed under the basic encoder-decoder framework, in which MobileNet v2 is adopted as the backbone network, due to its few parameters and low computational complexity. The high-level semantic information and low-level positional information are combined together to detect the tongue body’s boundary. And the dilated convolution operations are performed on the final feature maps of the network to enlarge the receptive field, so as to capture rich global semantic information. An attention mechanism is embedded to re-calibrate the feature maps spatially and channel-wise to enhance important features for the segmentation task, while suppressing the irrelevant ones. Moreover, a supervision output is added to each level of the decoder to guide the network to capture both the local and global image features for accurate tongue image segmentation. All supervision outputs are fused to produce good segmented results. The quantitative and qualitative results on two tongue datasets indicate that the proposed network can achieve a competitive performance with smaller model size and lower computational cost. The proposed method could accurately extract the tongue body, which can fully meet the requirements of practical applications. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
