In recent years, data-driven deep networks have demonstrated remarkable detection performance for infrared small targets. However, continuously increasing the depth of neural to enhance has proven impractical. Consequently, integration prior physical knowledge related targets within become crucial. It aims improve models’ awareness inherent characteristics. this paper, we propose a novel dual-d...
in this paper, first we develop the duality concept for $g$-bessel sequences and bessel fusion sequences in hilbert spaces. we obtain some results about dual, pseudo-dual and approximate dual of frames and fusion frames. we also expand every $g$-bessel sequence to a frame by summing some elements. we define the restricted isometry property for $g$-frames and generalize some resu...
in this paper the concept of homothetic dual exponential motions in d3 is discussed and theirvelocities obtained. due to the way in which the matter is presented, the paper gives some formula and factsabout dual exponential motions which are not generally known
in this paper, two new hamilton operators are defined and the algebra of dual split quaternions isdeveloped using these operators. it is shown that finite screw motions in minkowski 3-space can be expressedby dual-number ( 3×3 ) matrices in dual lorentzian space. moreover, by means of hamilton operators, screwmotion is obtained in 3-dimensional minkowski space 3r1
A novel Dual-polarization SAR ship target recognition method based on feature and loss fusion deep network is proposed in this paper, to improve the generalization ability, accuracy of imbalance samples, real-time performance general learning network. The combined composed two parts. first part region extraction lightweight mini Hourglass network, eliminate impact data background noise identifi...
Dual-axis electron microscopic tomography minimizes the missing wedge-induced resolution loss by taking two complementary tilt data sets of the same target along two orthogonal axes. The potential of this powerful approach has been hampered by the practical challenges inherent in finding the original targets that are dramatically displaced due to non-eucentric specimen rotation. Not only is the...
Eye movements were monitored to examine search efficiency and infer how color is mentally represented to guide search for multiple targets. Observers located a single color target very efficiently by fixating colors similar to the target. However, simultaneous search for 2 colors produced a dual-target cost. In addition, as the similarity between the 2 target colors decreased, search efficiency...
