Indian Conference on Computer Vision, Graphics & Image Processing (ICVGIP)
作者: Nilanjan Ray Baidya Nath Saha Hong Zhang Department of Computing Science University of Alberta Canada
We consider here a change detection problem: to find regions of change on a test image with respect to a reference image. Unlike the state-of-the-art change detection and background subtraction algorithms that compute... 详细信息

26th IEEE Conference on Computer Vision and Pattern Recognition (CVPR 2008), vol.4
作者: Necmiye Ozay Mario Sznaier Octavia I. Camps Department of Electrical and Computer Engineering Northeastern University Boston MA USA
This paper presents a general method for segmenting a vector valued sequence into an unknown number of sub-sequences where all data points from a subsequence can be represented with the same affine parametric model. T... 详细信息

International Conference on Convergence Information Technology
作者: Z. Y. Wu H. Y. Yu B. Tang University of Electronic Science and Technology China
The coding efficiency of AVS-P2 for the video sequences, which have many scene changes, is generally low. If the scene changes are taken into consider for video compression, the encoding performance can be improved. A... 详细信息

IEEE International Conference on Image Processing
作者: Zhi Li Guizhong Liu School of Electronics and Information Engineering Xi'an Jiaotong University Xi'an China
This paper proposes a novel scene change detection algorithm based on the 3D wavelet transform. In scene change including cut, dissolve and fade, the frames have particular temporal and spatial layouts. The dissolve a... 详细信息

IEEE International Symposium on Geoscience and Remote Sensing (IGARSS)
作者: Karin Griffis Maja Bystrom Department of Electrical and Computer Engineering Boston University USA
In this paper, two unsupervised methods for multi-band change detection are presented. Both methods model the multi-band difference image histogram in order to characterize different degrees of observed spectral chang... 详细信息

European conference on synthetic aperture radar
作者: Lars M.H. Ulander Mikael Lundberg Swedish Defence Research Agency (FOI) Link?ping Sweden FOI Sweden
This paper describes models which can be used to evaluate change detection algorithms based on multiple SAR images in the VHF- and UHF-band. The models are evaluated using a processed SAR data set acquired with the ai... 详细信息

IEEE International Symposium on Geoscience and Remote Sensing (IGARSS)
作者: Jason Fritz V. Chandrasekar Electrical & Computer Engineering Department Colorado State University Fort Collins CO USA
One of the most promising applications of synthetic aperture radar (SAR) imagery is change detection. However, the success of change detection algorithms is highly dependent on the type of change being detected. With ... 详细信息

IEEE International Symposium on Geoscience and Remote Sensing (IGARSS)
作者: Tarek Habib Jordi Inglada Gregoire Mercier Jocelyn Chanussot GIPSA-Laboratory CNRS INP Grenoble France Centre national détudes spatiales (Cnes-DCT/SI/AP) CNRS FRE 3167 LabSTICC/CID Institut TelecomTelecom Bretagne France
In the context of change detection and due to the multitude of change scenarios, the objective is to build a generic change detection system. For many technical and operational reasons the Support Vector Machines (SVM... 详细信息
