Stripe nonuniformity is very typical in line infrared focal plane arrays (IR-FPA) and uncooled staring IR-FPA. In this paper, the mechanism of the stripe nonuniformity is analyzed, and the gray-scale co- occurrence matrix theory and optimization theory are studied. Through these efforts, the stripe non uniformity correction problem is translated into the optimization problem. The goal of the optimization is to find the minimal energy of the image’s line gradient. After solving the constrained nonlinear opti mization equation, the parameters of the stripe nonuniformity correction are obtained and the stripe nonuniformity correction is achieved. The experiments indicate that this algorithm is effective and efficient.
