abstract = "Recently, the real-time monitoring of the urban ecosystem has
raised the attention of many municipal forestry management
services. The proper maintenance of trees is seen as crucial to
guarantee the quality and safety of the streetscape. However, the
current analysis still involves the time-consuming fieldwork
conducted for extracting the measurements of each part of the
tree, including the angle and diameter of the trunk, to cite a
few. Therefore, real-time monitoring is thoroughly necessary for
the rapid identification of the constituent parts of the trees in
images of the urban environment and the automatic estimation of
their physical measures. This paper presents a method to segment
the tree trunks in photographs of the municipal regions. To
accomplish such a task, we introduce a semantic segmentation
convolutional neural network architecture that incorporates a
depthwise residual block to the well-known U-Net model to reduce
the parameters required to create the network. Then, we perform a
post-processing step to refine the segmented regions by removing
the additional binary areas not related to the tree trunk. Lastly,
the proposed method also extracts the central line of the
identified region for future computation of the trunk
measurements. Compared with the original U-Net architecture, the
obtained results confirm the robustness of the proposed
approaches, including similar evaluation metrics and the
significant reduction of the network size.",
