Abstract Salient object detection is used as a pre-process in many computer vision tasks (such salient segmentation, video detection, etc.). When performing depth information can provide clues to the location of target objects, so effective fusion RGB and feature important. In this paper, we propose new aggregation approach, weighted group integration (WGI), effectively integrate information. W...

Abstract This paper aims at deriving some weighted Hardy type and Rellich inequalities with sharp constants on the Heisenberg group. The improved versions of these are established as well. technique adopted involve application elementary vectorial properties

For a finite abelian group G with exp(G)=n and an integer k≥2, Balachandran Mazumdar (2019) introduced the extremal function fG(D)(k) which is defined to be min{|A|:0̸≠A⊆[1,n−1] withDA(G)≤k} (and ∞ if there no such A), where DA(G) denotes A-weighted Davenport constant of G. Denoting by f(D)(p,k) when G=Fp (for p prime), it known (Balachandran Mazumdar, 2019) that p1/k−1≤f(D)(p,k)≤O(plogp)1/k hol...
