Abstract The current study examined upper elementary school children’s frequent, efficient and adaptive use of direct subtraction ( DS ) by addition SBA when mentally solving multi-digit subtractions, replicating expanding previous research Torbeyns et al. (2018). First, children were offered subtractions in two choice conditions which they had to indicate whether would or solve each item. In t...

Generally human vision system searches for salient regions and movements in video scenes to lessen the search space and effort. Using visual saliency map for modelling gives important information for understanding in many applications. In this paper we present a simple method with low computation load using visual saliency map for background subtraction in video stream. The proposed technique i...

Moving object detection and tracking (MODT) is the major challenging issue in computer vision, which plays a vital role many applications like robotics, surveillance, navigation systems, militaries, environmental monitoring etc. There are several existing techniques, has been used to detect track moving Surveillance system. Therefore it necessary develop new algorithm or modified robust work bo...

In background subtraction, the maintenance of significant backgrounds is very critical under various scene changes. In this paper, we propose a background maintenance method for dynamic scenes including global intensity level changes caused by the changes of illumination conditions and camera settings. If global intensity level changes abruptly, the conventional background model cannot discrimi...
