Spatially Prioritized and Persistent Text Detection and Decoding

  title={Spatially Prioritized and Persistent Text Detection and Decoding},
  author={Hsueh-Cheng Wang and Yafim Landa and Maurice F. Fallon and Seth J. Teller},
We show how to exploit temporal and spatial coherence to achieve efficient and effective text detection and decoding for a sensor suite moving through an environment in which text occurs at a variety of locations, scales and orientations with respect to the observer. Our method uses simultaneous localization and mapping (SLAM) to extract planar “tiles” representing scene surfaces. Multiple observations of each tile, captured from different observer poses, are aligned using homography… CONTINUE READING
