Description: A novel higher order singular value decomposition (HOSVD)-
based image fusion algorithm is proposed. The key points are given as follows:
1) Since image fusion depends on local information of source images,
the proposed algorithm picks out informative image patches of source images
to constitute the fused image by processing the divided subtensors
rather than the whole tensor 2) the sum of absolute values of the coefficients
(SAVC) from HOSVD of subtensors is employed for activity-level
measurement to evaluate the quality of the related image patch and 3) a
novel sigmoid-function-like coefficient-combining scheme is applied to construct
the fused result. Experimental results show that the proposed algorithm
is an alternative image fusion approach.-A novel higher order singular value decomposition (HOSVD)-

Description: This paper presents an adaptive information fusion method to improve the
accuracy and reliability of the altitude measurement information for small unmanned aerial
rotorcraft during the landing process. Focusing on the low measurement performance of
sensors mounted on small unmanned aerial rotorcraft, a wavelet filter is applied as a
pre-filter to attenuate the high frequency noises in the sensor output. Furthermore, to
improve altitude information, an adaptive extended Kalman filter based on a maximum a
posteriori criterion is proposed to estimate measurement noise covariance matrix in real
time. Finally, the effectiveness of the proposed method is proved by static tests, hovering
flight and autonomous landing flight tests. Platform: |
