摘要：

Stripe non-uniformity commonly exists in infrared focal plane array (IRFPA). The current study develops a scene-based stripe non-uniformity correction (NUC) method using only a single image. Efforts were made to translate the stripe NUC problem into a gradient-constrained optimization problem. The optimization aims to seek the optimal image with a vertical gradient as close to the original image as possible and make the energy of the horizontal gradient as small as possible. The experiments indicate that the proposed algorithm can provide enhanced results effectively and efficiently. (c) 2013 Elsevier B.V. All rights reserved.
