Postal envelope address block location by fractal-based approach

L.F. Eiterer, J. Facon, D. Menoti
Proceedings. 17th Brazilian Symposium on Computer Graphics and Image Processing  
For each envelope image, the ideal result (ground-truth segmentation) regarding each class has been generated.  ...  First, the fractal dimension of each pixel of a postal envelope image is computed using the 2D variation procedure.  ...  Yonekura et al [14] present a method for postal envelope segmentation combining the 2-D histogram and morphological clustering.  ...
