Robust zebra-crossing detection using bipolarity and projective invariant
Mohammad Shorif Uddin, Tadayoshi Shioyama · 2006
Crossing roads is a great challenge for visually impaired people. A robust technique for detection of zebra crossings is described. This is achieved through bipolaritybased segmentation and projective invariant-based recognition. The technique shows good performances under various illuminations such as sunny, cloudy and rainy situations in the day time and also evening and night environments.
