Energy efficiency is the most important issue in wireless sensor networks. To reduce energy consumption, lots of aggregation algorithms were proposed. Since the overlap of detect regions, data aggregation has been extensively investigated for eliminating data redundancy, but it has a great side-effect (such as: latency, accuracy, fault-tolerance). In this paper, we take energy efficiency and latency...
Shape representation is a very important issue in computer vision and pattern recognition. This paper presents a novel shape representation algorithm based on equilateral polygonal approximation. Firstly, the problem and definition of equilateral polygonal approximation are presented in this paper. Then a new equilateral polygonal approximation method based on detecting optimal edge length using genetic...
According to the calibration of binocular vision, an improved two-stages camera calibration method involved with multi-distortion coefficients is introduced in this paper. It takes the sum of distance in the world coordinate between ground truth 3D points and calculated 3D points as cost function which is optimized by evolution algorithm (EA). The 3D pointspsila coordinate are calculated by the imitated...
