Interframe phase-correlated registration scene-based nonuniformity correction technology

摘要

In this paper, we propose an interframe phase-correlated registration scene-based nonuniformity correction technology. This technology is based on calculating the correlated phase information between two neighboring frames to determine the precise overlapping area of them. Usually, the common registration algorithms use the scene motion information to calculate the relative displacement of neighboring frames to determine the overlapping area. This approach may be interfered by the level of nonuniformity and cause the registration error. Furthermore, bring negative consequences to the correction process. Our technology effectively conquers this worry, and makes the level of nonuniformity careless during the registration process, We also adopt a new gain coefficient convergent method which proposed by our lasted study to finish the correction. The whole technology works with great performance. Detailed analysis, images and flow charts of this technology are also provided. (C) 2015 Elsevier B.V. All rights reserved.
