IEEE International Conference on Image Processing
作者: Sang Hyun Kim Rae-Hong Park Department of Electronic Engineering Sogang University Seoul South Korea
In huge video databases, an effective video indexing method is required. While manual indexing is the most effective approach to this goal, it is slow and expensive. Thus automatic indexing is desirable, and previousl... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: N. Vaswani ECE Department Georgia Institute of Technology Atlanta GA USA
We study the change detection problem in a general HMM when the change parameters are unknown and the change can be slow or drastic. Drastic changes can be detected easily using the increase in tracking error or the n... 详细信息

International Workshop on the Analysis of Multi-temporal Remote Sensing Images (MultiTemp)
作者: Luis M.T. de Carvalho Fausto W. Acerbi Jose R. Scolforo Jose M. de Mello Antonio D. de Oliveira Federal University of Lavras Lavras Brazil
Our objective was to develop a procedure for change detection which is less sensitive to problems caused by misregistration, atmospheric effects and variations in vegetation phenology. The procedure is based on redund... 详细信息
