UV-SAM: Adapting Segment Anything Model for Urban Village Identification

Understand

Urban villages, defined as informal residential areas in or around urban centers, are characterized by inadequate infrastructures and poor living conditions, closely related to the Sustainable Development Goals (SDGs) on poverty, adequate housing, and sustainable cities.

• Traditionally, governments heavily depend on field survey methods to monitor the urban villages, which however are time-consuming, labor-intensive, and possibly delayed.
• Thanks to widely available and timely updated satellite images, recent studies develop computer vision techniques to detect urban villages efficiently.
• However, existing studies either focus on simple urban village image classification or fail to provide accurate boundary information.
