    • Line detection using Wavelet filters 

      Udomhunsakul, Somkait; Kozaitis, S.P.; Sritheeravirojana, Uthai Thai (2003-09-25)
      We proposed a new line detection method in noisy images using Mexican hat wavelet filters. In our approach, we applied the wavelet transform in a multiresolution sense by forming the products of wavelet coefficients at the ...
    • Linear feature detection using multiresolution wavelet filters 

      Kozaitis, S.P.; Udomhunsakul, Somkait; Cofer, Rufus H.; Agarawal, A.; Song, Shuwu (2002-08-06)
      We detected roads in aerial imagery based on multiresolution linear feature detection. Our method used the products of wavelet coefficients at several scales to identify and locate linear features. After detecting possible ...
    • Semi-automatic road extraction from aerial images 

      Udomhunsakul, Somkait; Kozaitis, Samuel P.; Sritheeravirojana, Uthai Thai (2004-02-13)
      In this work, we proposed a method to detect roads in aerial imagery. In our approach, we applied the wavelet transform in a multiresolution sense by forming the products of wavelet coefficients at the different scales to ...
