To achieve this objective, we propose two methodologies. First, we propose to improve the robustness by leveraging the local geometry inherent in pavement data. To this end, we propose the Dense Local Geometry (DLG) features. These features are incorporated as an additional input to the CNN, providing the network with a sense of local geometry that is tailored specifically to cracks during training. Second, we propose to enhance the detail-preserving capability by introducing the Boundary Enhancement (BE) loss. The BE loss constructs a supervisory signal on the boundaries of segmentation regions, enhancing the network\u2019s capability to perceive small deviations and disconnectivity at the boundary of cracks during training. The outcomes of this research will support transportation agencies in achieving detailed pavement condition assessments by providing high-granularity and precise crack segmentation from pavement range images collected with the emerging 3D laser technology.\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Advancing Deep Learning for Pavement Crack Segmentation with Dense Local Geometry Features and Boundary Enhancement Loss "}],"uid":"28475","created_gmt":"2023-05-11 20:58:08","changed_gmt":"2023-05-11 20:58:08","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-06-13T09:00:00-04:00","event_time_end":"2023-06-13T11:00:00-04:00","event_time_end_last":"2023-06-13T11:00:00-04:00","gmt_time_start":"2023-06-13 13:00:00","gmt_time_end":"2023-06-13 15:00:00","gmt_time_end_last":"2023-06-13 15:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Online","extras":[],"related_links":[{"url":"https:\/\/teams.microsoft.com\/l\/meetup-join\/19%3ameeting_YzY5Mzk0ZTctYzczYS00OGFiLWI2ZTEtMmQ0MmQyNTczNjI5%40thread.v2\/0?context=%7b%22Tid%22%3a%22482198bb-ae7b-4b25-8b7a-6d7f32faa083%22%2c%22Oid%22%3a%22b682b020-7cda-4227-a840-88deeed12026%22%7d","title":"Microsoft Teams Meeting link"}],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"192484","name":"PhD Defense, graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
