Abstract

Abstract

Blind pixels often appear in infrared focal plane arrays owing to the influence of the manufacturing technology. The previously used single-band blind element compensation algorithm is not satisfactory for large blind clusters and blind pixels at edge positions. With the rise in double-band thermal images, a blind element compensation algorithm based on double-band information is proposed in this study. This algorithm combines the information from the two bands. Different strategies are used to compensate for the blind pixels in the image, according to the similarity of the neighborhood information of the two bands. This can effectively compensate for the large blind clusters in the image and the blind pixels at the edge using different strategies.
