in this paper, we aim to overcome three major shortcomings of the fdh (free disposal hull) directional distance function through developing two new, named linear and fractional cdfdh, complete fdh measures of efficiency. to accomplish this, we integrate the concepts of similarity and fdh directional distance function. we prove that the proposed measures are translation invariant and unit invari...

Background estimation is an efficient infrared (IR) small target detection method. However, to deal with unknown targets, the window in existing algorithms should be adjusted perform multiscale and requires a lot of calculations. Besides, stages during after have received wide attention algorithms, but research on before insufficient. Moreover, typically regard maximum value different orientati...

For localisation of unknown non-cooperative targets in space, the existence interference points causes inaccuracy pose estimation while utilizing point cloud registration. To address this issue, paper proposes a new iterative closest (ICP) algorithm combined with distributed weights to intensify dependability and robustness target localisation. As space have not yet been extensively studied, we...

Recall that in the closest vector problem we are given a lattice and a target vector (which is usually not in the lattice) and we are supposed to find the lattice point that is closest to the target point. More precisely, one can consider three variants of the CVP, depending on whether we have to actually find the closest vector, find its distance, or only decide if it is closer than some given...
