 MODIS 1B影像中存在横向和纵向条带,基于均衡化曲线补偿技术,提出了一种快速检测和去除条带的算法,给出了条带检测判定参数,即:如果A帧和B帧的10组传感器校正系数C_i值分别位于0的两侧,且ABS(C_i)>0.008,则存在宽条带;如果10组传感器的校正系数MAX(C_i)>0.05时,则存在单行条带。去除宽条带时,需以当前列为首列,从其后连续的100列影像中提取各传感器相对当前列的校正系数。结果表明,条带检测模型能有效识别单行条带和宽条带,多行条带需目视识别,单行条带和宽条带去除效果明显好于NASA网站公布数据,多行条带虽未彻底去除,但处理后的影像质量得到明显改善。 更多还原

【Abstract】 The MODIS sensor has 36 spectral bands,the desired effect can not be obtained with only one destriping method. Based on compensation and elimination of equalization curve method,a new set of algorithm is proposed in this article to rapidly detect and remove stripes,through giving a definite judging parameter of the stripe.If the correcting coefficient of 10 groups sensors in A-frame and B-frame are separated by 0,and the ABS(C_i)>0.008,then there exist wide stripes.If the maximum correcting c... 更多还原
