Hamiltonian Path based Shadow Removal

  title={Hamiltonian Path based Shadow Removal},
  author={Cl{\'e}ment Fredembach and Graham D. Finlayson},
For some computer vision tasks, the presence of shadows in images can cause problems. For example, object tracks can be lost as an object crosses over a shadow boundary. Recently, it has been shown that it is possible to remove shadows from images. Assuming that the location of the shadows are known, shadow-free images are obtained in three steps. First, the image is differentiated. Second, the derivatives at the shadow edge are set to zero. Third, reintegration delivers an image without… CONTINUE READING
