Abstract: Based on the analysis to the behavior of blind pixel, an auto-searching and interpolation compensation algorithm for blind pixels by using IRFPA’s imaging data of two reference radiation source and the pertinency between the adjacent pixels is advanced. Then auto-searching and compensation for blind pixels of IRFPA is achieved. The experiments on real Infrared imaging sequences demonstrate that the algorithm has the advantages of apace and high veracity for blind pixels location, good correction effect and easy implementation.
