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. Platform: |

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. Platform: |

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. Platform: |

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

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-This example shows how to perform automatic detection and motion-based
tracking of moving objects in a video a stationary camera.

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 Platform: |

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. Platform: |
