New LoDEOT method improves building footprint extraction from imagery

By PulseAugur Editorial · [1 sources] ·

Researchers have developed LoDEOT, a novel method for extracting building footprints from off-nadir imagery. This approach utilizes a compact, five-dimensional offset token instead of high-dimensional instance tokens, which can learn task-relevant representations through end-to-end training. Experiments on multiple datasets demonstrate LoDEOT's effectiveness, achieving superior performance in roof detection and footprint correction metrics compared to existing end-to-end methods. AI

IMPACT Introduces a more efficient method for extracting building footprints from imagery, potentially improving geospatial analysis.

    LoDEOT: Low-Dimensional and Efficient Offset Tokens for Building Footprint Extraction from Off-Nadir Imagery

    arXiv:2610.05899v2 Announce Type: replace Abstract: Instance-level roof-to-footprint offset (RFO) prediction is central to extracting building footprints from off-nadir imagery. Query-based pipelines commonly use high-dimensional instance tokens to predict signed two-dimensional …
