A Simple Heuristic for Classification with Ant-Miner Using a Population 蚁群分类的一种简单启发式算法
Hongxing Wu, Kai Sun
Ant-Miner is an Ant Colony Optimization algorithm for classification task. This paper proposes an improved version of Ant-Miner, named mAnt-Miner+, which is based on mAnt-Miner (Ant-Miner that uses a population of many ants). mAnt-Miner+ uses a simple and invariable heuristic strategy, that avoids it easily trapping in the local optimal solution and improves the efficiency of the algorithm. mAnt-Miner+ has been compared against Ant-Miner and mAnt-Miner in six public domain data sets. The results show that: 1) in term of predictive accuracy, mAnt-Miner+ is competitive with Ant-Miner and better than mAnt-Miner; 2) mAnt-Miner+ is faster than Ant-Miner and mAnt-Miner; 3) the difference of the rule simplicity between three algorithms is small.

Feng Zhao, Zengru Jiang
3D vision location is one of the most famous researches in computer stereo vision area. However, the traditional algorithm is not only complicated but low-matched. We proposed a new algorithm in this article: First of all, we use Zhang Zhengyou camera calibration methods for vision calibration. Secondly, Epipolar constraint, NCC similarity measure and disparity gradient compatibility are individually used in different stages of sparse feature based stereo matching. The last, least squares space coplanar approximation is used to obtain the 3D coordinates of matching points. It has been proved not only operated easily but provided with high stability and robustness.

Fast Template Matching Using Pruning Strategy with Haar-like Features 基于Haar-like特征剪枝策略的快速模板匹配
Vinh-Tiep Nguyen, Khanh-Duy Le, M. Tran, A. Duong
Template matching is one of the most popular problems in computer vision applications. Many methods are proposed to enhance the accuracy and performance in terms of processing time. With the rapid development of digital cameras/recorders and HD video, images captured by modern devices have much higher resolution than before. Therefore it is necessary to have novel real-time processing template matching algorithms. This motivates our proposal to improve the speed of matching an arbitrary given template, especially in a large size image. Our key idea is based on a pruning strategy to remove certain unmatchable positions in a large size image with only a few simple computational operations. Our proposed method has a flexibility for users to select various dissimilarity measures to increase the accuracy of the system in practical applications. Experiments show that our algorithm is faster than the standard algorithm implemented in OpenCV using Fast Fourier Transform about 8 to 10 times.
模板匹配是计算机视觉应用中最热门的问题之一。在处理时间方面,提出了许多提高精度和性能的方法。随着数码相机/录像机和高清视频的迅速发展,现代设备拍摄的图像分辨率比以前高得多。因此,有必要开发新的实时处理模板匹配算法。这促使我们提出提高匹配任意给定模板的速度,特别是在大尺寸图像中。我们的关键思想是基于修剪策略,通过一些简单的计算操作来删除大尺寸图像中某些不匹配的位置。在实际应用中,我们提出的方法使用户可以灵活地选择各种不相似度量,以提高系统的准确性。实验表明,该算法比OpenCV中使用快速傅里叶变换实现的标准算法快8 ~ 10倍。

Interactive 3D Image Processing System for iPad iPad交互式3D图像处理系统
Mengyu Yuan, Weiqing Li
As the most popular tablet computer, iPad is designed for audio-visual media, entertainment, and a variety of applications. However, because of the limited memory resource, it's difficult to implement volume rendering algorithm on iPad. Volume rendering directly displays stereoscopic images from 3D data set, so it is widely used in the field of biology and medicine. In this paper, an optimized Maximum Intensity Projection (MIP) volume rendering algorithm is proposed to reduce resource usage significantly. Four clusters of viewpoints are used to optimize the cell removal process. Twice scans in opposite directions are performed for each cluster of viewpoints to remove the useless cells thoroughly, thus to reduce the memory cost. Based on the optimized algorithm, an interactive 3D image processing system for iPad is implemented.
