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 coefficient(C’
i
) of 10 groups sensors is greater than 0.05
then there exist single-line stripes.The wide destriping process is as follows.Take the current column as the first one;then extract the correcting coefficient from the next 100 columns of each sensor compared with the first column seperatively.The results show that the detecting model can effectively identify the single-line stripes and the wide stripes
but the multi-line stripes need visual assistant.The removal effect of the single-line and the wide stripes is better than that from NASA website
the image quality is significantly improved after the treatment
though multi-line stripes are not completely removed.
