Real-time segmentation of moving regions in image sequences is a fundamental step in many vision systems including automated visual surveillance, human-machine interface, and very low-bandwidth telecommunications. A typical method is background subtraction. Many background models have been introduced to deal with different problems. One of the successful solutions to these problems is to use a ...

LMOST two decades ago, one of us (DOBZHANSKY 1924) found that some A mutant strains of Drosophila melanogaster differed from each other and from normal flies in certain details of the structure of their genitalia. The mutants concerned were known to affect the eye color (white, ivory), body color (ebony, yellow), eye size (Bar), and bristle shape (forked), but the existence of differences in th...

In this paper, for the modern intelligent video surveillance, we introduce an optimizing motion detection algorithm aim at overcoming the flaw of conventional background subtraction algorithm. We combine adaptive background model in HSV color space with moving object segmentation based on fuzzy clustering to extract moving objects from frame. The adaptive background model is able to restoring t...

This experimental investigation replicates previous investigations of the effects of left margin screen background color hue to signal lesson sections on declarative knowledge and extends those investigations by adding a measure of structural knowledge. Participants (N = 80) were randomly assigned to receive one of four computer-based lesson treatments that consisted of color or no color lesson...
