Thresholding for change detection
Sixth International Conference on Computer Vision (IEEE Cat. No.98CH36271), 2002Summary: Image differencing is used for many applications involving change detection. Although it is usually followed by a thresholding operation to isolate regions of change there are few methods available in the literature specific to (and appropriate for) change detection. We describe four different methods for selecting thresholds that work on very

Detecting changes in XML documents
Proceedings 18th International Conference on Data Engineering, 2003We present a diff algorithm for XML data. This work is motivated by the support for change control in the context of the Xyleme project that is investigating dynamic warehouses capable of storing massive volumes of XML data. Because of the context, our algorithm has to be very efficient in terms of speed and memory space even at the cost of some loss ...

Change: Detection and Modification
Applied Psychophysiology and Biofeedback, 2001Because human physiology is always changing, one of the challenges for those interested in biofeedback applications is how to establish techniques to determine if the biofeedback has altered the physiology. This paper explores some of the areas of concern and some solutions that have been reported.

Meaningful Change Detection on the Web⋆
2001In this paper we present a new technique for detecting changes on the Web. We propose a new method to measure the similarity of two documents, that can be efficiently used to discover changes in selected portions of the original document. The proposed technique has been implemented in the CDWeb system providing a change monitoring service on theWeb ...

Synergistic Change Detection and Tracking
IEEE Transactions on Circuits and Systems for Video Technology, 2015Visual tracking in image streams acquired by static cameras is usually based on change detection and recursive Bayesian estimation, such an approach laying at the core of many practical applications. Yet, the interaction between the change detector and the Bayesian filter is typically designed heuristically.

Techniques ror Change Detection
IEEE Transactions on Computers, 1972The problem of change detection presents itself for imaging systems that view the same scene repeatedly. Current research programs based on the processing of side-looking radar imagery show that spatial alignment of the various parts of the image must be highly accurate if noise in the difference picture is to be reduced to acceptably low levels ...
