- •
We present a background suppression method based on multiscale random projection.
- •
Nonsubsampled pyramid is applied to separates the background and targets.
- •
The proposed method can not only efficiently reduce the spatial redundancy but also preserve target information.
- •
Both background suppression and target enhancement can be achieved by computing Mahalanobis distance in the proposed method.
