Children engage with their imaginative faculties in a variety of ways as they grow and develop. Th ey play simple pretend games starting at about the age of two (Fein, 1981; Nicolich, 1977; Singer & Singer, 1990), which are then elaborated into longer pretend sequences and sometimes into ongoing relationships with imaginary companions (Taylor, 1999) and paracosms (see chapter 27). Children also...

This paper describes a system for the recovery in real-time of the pose of moving polyhedral objects using modest hardware. A method of line tracking first introduced by Harris is extended to multiple calibrated cameras, and afforced by robust methods and filtering. The system, which uses three cameras a low-end commercial framegrabber and runs on single PC, has been devised to provide simple v...

This paper proposes a novel image mosaic method based on SIFT (Scale Invariant Feature Transform) feature of line segment, aiming to resolve incident scaling, rotation, changes in lighting condition, and so on between two images in the panoramic image mosaic process. This method firstly uses Harris corner detection operator to detect key points. Secondly, it constructs directed line segments, d...

A high precision epipolar line restoration algorithm based on Multipopulation Cooperative PSO (MCPSO) is proposed in this paper. It adopts Harris operator to extract corner point and finishes gray cross -correlation matching. Firstly, the fundamental matrix initial value between matches in two images is calculated by 8 pairs matches algorithm. And then the optimal value of this matrix is gotten...

In this paper, a methodology for ROI extraction in INDT using multi-resolution analysis is proposed. Complementary, both local procedures Harris operator and gradient direction are used. The proposed methodology is tested using three CFRP specimens having complex shapes and defects at different depths. Besides, another two specimens are considered, which are made of PlexiglasTM and aluminum wit...

Abstract Many real-world problems demand optimization, minimization of costs and maximization profits, meta-heuristic algorithms have proficiently proved their ability to achieve optimum results. This study proposes an alternative algorithm Lévy Flight Distribution (LFD) by integrating Opposition-based learning (OBL) operator, termed LFD-OBL, for resolving intrinsic drawbacks the canonical LFD....
