| 摘 要： | 为解决红外焦平面阵列的非均匀性噪声制约红外成像质量问题,提出基于场景的神经网络非均匀性校正算法,利用帧间运动的图像序列实现非均匀性校正.先采用基于投影的运动估计算法选取神经网络算法的学习参考帧,再进行偏置矩阵计算的基于帧间运动判断的神经网络非均匀性校正算法,有效克服了传统SBNNT由于运动不足产生的鬼影问题.算法已在以TMS320DM643为处理核心DSP硬件处理平台上实现,取得了较好的校正效果.

| Abstract: | The non-uniformity in the infrared focal plane array has limited the quality of infrared imaging system.Scene-based neural networks(SBNNT)non-uniformity correction(NUC) techniques correct the non-uniformity by using an image sequence and relying on motion between frames.An improved SBNNT non-uniformity correction of IRFPA is proposed to eliminate the ghost artifact.Linear interpolation projection-based shift estimation(LIPSE)algorithm is used to select frames for learning and the offset matrix of SBNNT was ... |
