Rapid, direct, and trace detection of explosives in an open environment is of particular need in homeland and/or transportation security. In this work, an aerodynamic assisted thermo desorption mass spectrometry method was developed for the direct quantitative analyses of explosives from a distance. Remote non‐volatile explosive sensing was achieved for 2, 4, 6‐trinitrotoluene, trinitrohexahydro‐1,...
This paper proposes a remote sensing image pan-sharpening method from the perspective of low-rank and sparse matrix decomposition. Based on the characteristic of multispectral (MS) images, the low spatial resolution information of MS images is modeled as low-rank, and the high spectral resolution information of MS images is modeled as sparse. First, the low-rank and sparse matrix decomposition algorithm...
In this paper, a novel approach is proposed for unsupervised change detection of multitemporal remote sensing images. The proposed method is able to produce the change detection result on the difference image without a priori assumptions .Firstly, the difference image which is acquired from multitemporal images. Mean shift algorithm is used to reduce noise of difference image and fake change. Then...
In the detection of change objects of SAR images, regard to the images containing high intensity noise, traditional methods will produce a considerable false alarm. This paper presents a new method of change detection based on directional information. Direction measure is proposed to suppress noises and brighten object contours. Then region blocks which contain changing objects are extracted according...
