Description
  • We consider region of interest (ROI) tomography of piecewise constant functions.We prove that continuous ROI data determine piecewise constant functions. Additionally,an algorithm is developed for ROI tomography of piecewise constant functionsusing a Haar wavelet basis. A weighted `p–penalty is used with weights that depend on therelative location of wavelets to the region of interest. We prove th... read more
