Paper Abstract

Infrared image quality is a key factor of object detection. Stripe nonuniformity is very typical in the staring infrared focal plane array (IRFPA). In this paper, we propose a novel high-space-frequency correction method to eliminate the stripe nonuniformity. The kernel ideal is to eliminate the high-space-frequency part of stripe nonuniformity and retain its low-space-frequency part which can reduce unwanted ghosting artifacts. Firstly, the spatial characteristic of stripe nonuniformity is discussed, then correction parameters are computed based on the spatial high frequency part of image. Experimental results show the proposed mehtod can compute adaptive correction parameters of each readout channel and obtain a reliable stripe nonuniformity reduction.
