Whether for purposes of compression eeciency, image editing, interactive multimedia authoring, or database search, it is often useful to be able to segment images or image sequences into regions corresponding to objects. In this paper we describe a segmentation scheme that takes account of multiple image characteristics, developing a multi-modal statistical(More)
SeeCoast extends the US Coast Guard Port Security and Monitoring system by adding capabilities to detect, classify, and track vessels using electro-optic and infrared cameras, and also uses learned normalcy models of vessel activities in order to generate alert cues for the watch-standers when anomalous behaviors occur. SeeCoast fuses the video data with(More)
Hyperlinked video is video in which speciic objects are made selectable by some form of user interface, and the user's interactions with these objects modify the presentation of the video. Identifying and tracking the objects remains one of the chief diiculties in authoring hyperlinked video; we solve this problem through the use of a video tracking and(More)

Fourier analysis is often thought of as a technique for measuring the spectral content of a signal over the period in which the signal was measured. In this column, we discuss techniques that allow you to use Fourier analysis to provide accurate measurements of the instantaneous frequency of a signal. We discuss the short-time Fourier transform and its main(More)
