pdipm_diff

PURPOSE ^

PDIPM_DIFF inverse solver for difference data using Primal/Dual interior point method

SYNOPSIS ^

function img=pdipm_diff( varargin )

DESCRIPTION ^

 PDIPM_DIFF inverse solver for difference data using Primal/Dual interior point method
 img= ab_pdipm( inv_model, data1, data2)
 img        => output image (or vector of images)
 inv_model  => inverse model struct
 data1      => differential data at earlier time
 data2      => differential data at later time

  inv_model.pdipm_diff.norm_data  1 or 2 (DEFAULT 2)
  inv_model.pdipm_diff.norm_image 1 or 2 (DEFAULT 2)
  inv_model.pdipm_diff.beta     (default 1e-6)

 Parameters:
  max_iters =  inv_model.parameters.max_iterations (default 10)
      Max number of iterations before stopping
  min change = inv_model.parameters.min_change   (default 0)
      Min Change in objective fcn (norm(y-Jx)^2 + hp*TV(x)) before stopping
 beta is the parameter that smooths the TV functional
