A new singular value decomposition (SVD) band-pass-filter technology is presented for background suppression and denoising in small targets detecting of visible images.Firstly
the relation between image singular value and targets
image noise and image background is analyzed.And results show that the high order part of image singular value obtains more information of image noise
the middle order part obtains more information of targets and the low order part obtains more information of image background.Based on this fact
two SVD band-pass-filters named SVD-I and SVD-II are proposed.And two filter parameters estimation methods are given
including singular value curve turning-point method and threshold criterion method.Experiments show that the new SVD band-pass-filter can suppress image background and denoising effectively
and improve the signal to noise (SNR) of small targets.
