[Special EffectsA_Homogeneous_Transform_Class_for_the_ITK.4

Description: Homogeneous transformations are widely used in computer vision and graphics. They commonly arise when considering the transformation of an image of a planar object under arbitrary camera motion, or the transformation of two images of the same scene due to camera motion holding the optical center fixed. In this paper we describe the addition of a class of homogeneous transforms for the Insight Toolkit.

[BooksA_registration_method_applicable_to_outdoor_AR_sys

Description: 主要阐述了一种适用于户外AR系统(augmented reality system)的注册方法;利用标记物计算初 始结构参数,并确定初始的共面自然特征点集;在后续的运行过程中, 通过相关系数法在相邻的两帧画面 中寻找候选匹配自然特征点对;采用了基于标记物提供的共面约束和 RANSAC(RANdom Sample Consensus)算法相结合的方法,从这些候选匹配点中选出满足共面条件的匹配点对;计算这些共面点所对 应的单应矩阵(Homography),进而求解相机的运动参数,完成虚拟物体的注册。该方法特别适合没有显式 平面结构的室外环境。 -In this paper, a kind of registration method applicable to outdoor AR system (augmented reality system) is elaborated. The plane marker is employed in calculating initial structure parameter natural features are tracked from the two adjacent frame through correlation and taken as candidate matches. A method Based on the constraint of marker and RANSAC (Random Sample Consensus) is adopted, so that good matches, which satisfy coplanar condition, are selected out of the candidate matches. Through the homographic matrix provided from the coplanar points, we could work out motion parameter of the camera, and finally finish registration of virtual objects. The registration method is most appropriate for outdoor surroundings with obscure plane structure.

[Software EngineeringMultiple-Pedestrian-Tracking-using-Colour-and-Mot

Description: This paper presents a method that combines colour and motion information to track pedestrians in video sequences captured by a fixed camera. Pedestrians are firstly detected using the human detector proposed by Dalal and Triggs which involves computing the histogram of oriented gradients descriptors and classification using a linear support vector machine. For the colour-based model, we extract a 4-dimensional colour histogram for each detected pedestrian window and compare these colour histograms between consecutive video frames using the Bhattacharyya coefficient. For the motion model, we use a Kalman filter which recursively predicts and updates the estimates of the positions of pedestrians in the video frames. We evaluate our tracking method using videos from two pedestrian video datasets from the web. Our experimental results show that our tracking method outperforms one that uses only colour information and can handle partial occlusion.

Description: Research in motion analysis has evolved over the years as a challenging field. Moving object detection and tracking is of major interest in applications such as traffic monitoring, military, medicine and biological sciences etc. In this a new algorithm is proposed for the detection and tracking of moving objects. The image sequence is taken from the digital camera. After preprocessing, the first two frames from the image sequence are segmented by using 8 component connectivity. ,Research in motion analysis has evolved over the years as a challenging field.

Description: 基于帧间差分的单目标/多目标的实时跟踪程序,基于MATLAB编写。希望对刚学习MATLAB的同学有所帮助-This example shows how to perform automatic detection and motion-based tracking of moving objects in a video a stationary camera. Copyright 2014 The MathWorks, Inc. Detection of moving objects and motion-based tracking are important components of many computer vision applications, including activity recognition, traffic monitoring, and automotive safety. The problem of motion-based object tracking can be divided into two parts: # detecting moving objects in each frame # associating the detections corresponding to the same object over time The detection of moving objects uses a background subtraction algorithm based on Gaussian mixture models. Morphological operations are applied to the resulting foreground mask to eliminate noise. Finally, blob analysis detects groups of connected pixels, which are likely to correspond to moving objects. The association of detections to the same object is based solely on motion. The mo

Description: This paper presents a simple technique for motion detection in steady-camera video sequences. It consists of three stages. Firstly, a coarse moving edge representation is computed by a set of arithmetic operations between a given frame and two equidistant ones (initially the nearest ones). Secondly, non-desired edges are removed by means of a filtering technique.
