Improved Reconstruction Quality of Bioluminescent Images by Combining SP₃ Equations and Bregman Iteration Method

Algorithm 1

BLT reconstruction with SP₃ equations and Bregman iteration method.

Initialization: 𝜀>0, 𝑘_max>0, 𝑘=1, 𝑣₁=0, and 𝑠

Construct the operator 𝐴 by solving SP₃ equations

 While 𝑠_𝑘+1−𝑠_𝑘/𝑠_𝑘+1<𝜀 or 𝑘<𝑘_max  do

  Solve (7): 𝑠_𝑘+1←argmin_𝑠≥0‖𝐴𝑠−(Φ^meas+𝑣_𝑛)‖²₂+𝜆⋅𝐽(𝑠)

  Update 𝑣_𝑘: 𝑣_𝑘+1←𝑣_𝑘+Φ^meas−𝐴𝑠_𝑘+1

  𝑘←𝑘+1

 End while
