Defective Pixel Correction - DPC

 

 

 

Overview
 
This IP corrects the defective pixel with interpolated values based on neighbor pixels of the same color channel.
 
 
Goal
 
Typical correction methods include detection of cold or hot pixels using either median or averaging estimation on immediate pixel neighborhood.
