An Image Registration Method for Colposcopic Images

Algorithm 1

Search algorithm.

Require: search radius SR, window size 𝑊

 for  𝑤𝑖𝑛𝑑𝑜𝑤=1 to 𝑊𝑀𝐴𝑋 in the reference image do

  for  𝑖𝑚𝑎𝑔𝑒=2 to 𝑛 in the sequence do

   Locate the position of 𝑤𝑖𝑛𝑑𝑜𝑤 in 𝑖𝑚𝑎𝑔𝑒

   Based on SR generate all possible neighbor-windows of 𝑤𝑖𝑛𝑑𝑜𝑤

   Evaluate the quality of 𝑤𝑖𝑛𝑑𝑜𝑤 and all neighbor-windows

   Select the window with the best quality value

   Locate this best window in the location of 𝑤𝑖𝑛𝑑𝑜𝑤 in 𝑖𝑚𝑎𝑔𝑒
