Fig. 1 Flowchart of the proposed approach for tracing multi-person The majority of conventional video tracking surveillance systems assumes a likeness to a person’s appearance for some time, and individuality of the person during tracking. However, illumination changes by weather or lighting and occlusions by overlapping people make tracking difficult. To address this situation, we use an adapt...

External impact load resistance of self-elevating (self-supporting) crossing frames (hereinafter referred to as “crossing frames”) is one the important mechanical properties. The risk and cost are high for studying influence rule a single parameter on external loads frame carrier cables by test method. To explore dropping wire position, height, distance type loads, parametric modeling method wi...

in this paper we get some results and applications for duals and approximate duals of g-frames in hilbert spaces. in particular, we consider the stability of duals and approximate duals under bounded operators and we study duals and approximate duals of g-frames in the direct sum of hilbert spaces. we also obtain some results for perturbations of approximate duals.

in this paper, g-dual function-valued frames in l2(0;1) are in-troduced. we can achieve more reconstruction formulas to ob-tain signals in l2(0;1) by applying g-dual function-valued framesin l2(0;1).
