Stripe nonuniformity correction based on registration for infrared-focal plane arrays
|
Abstract:
Stripe nonuniformity is a very typical fixed pattern noise in line infrared focal plane arrays (IR-FPA) and uncooled staring IR-FPA. The cause was analyzed and a stripe nonuniformity correction algorithm based on brightness constancy assumption and registration was proposed. Brightness mean-square errors function was obtained according to adjacent frames. Nonuniformity correction parameters could be gotten through the unique global optimum by minimizing the function. Experimental results indicate that the proposed algorithm could achieve a great convergence in several frames with low computational complexity and enhance the effective of stripe nonuniformity.
