==== using DIC 1 ====

this is based on variance. works ok.

</flow>




======using DIC 2 ========

based on floodfilling DIC outside. color intensity increases near embryo
so a lot of the outside comes with it. bg is not homogenous.

========== using RFP ==========

using floodfill. works quite well. suggests that a 3d threshold would do the job well.

======= using RFP =========

using percentile thres 2d. 
* works well later
* a lot of noise early, need something in addition

====== using DIC ===========

uses abs-grad on dic directly
fill holes
needs smoothing to fix jpeg artifacts

==== using DIC ==========

bilateral filter. dim 2,2, interval 10
