Abstract
Provided are a motion detection system and method. The motion detection system includes a pixel-based detector configured to compare a previous frame and a present frame to extract pixel constituting a first foreground region, a region-based detector configured to extract a second foreground region based on peripheral pixels of a pixel to be inspected, and a motion determiner configured to detect, as a final motion region among pixel groups of the first foreground region, a pixel group comprising pixels corresponding to the second foreground region.
Claims19
A motion detection system comprising:
- a pixel-based detector configured to compare a previous frame and a present frame to extract pixels constituting a first foreground region;
- a region-based detector configured to extract a second foreground region based on peripheral pixels of a pixel to be inspected;
- and
- a motion determiner configured to detect, as a final motion region among pixel groups of the first foreground region, a pixel group comprising pixels corresponding to the second foreground region.
A motion detection method comprising:
- comparing a previous frame and a present frame to extract pixels constituting a first foreground region;
- extracting a second foreground region based on peripheral pixels of a pixel to be inspected;
- and
- detecting, as a final motion region among pixel groups of the first foreground region, a pixel group comprising pixels corresponding to the second foreground region.
A non-transitory computer readable medium having recorded thereon a program, which when executed by a computer, causes the computer to execute a method comprising:
- detecting a pixel-based foreground region by comparing a current image frame and a previous image frame;
- detecting a region-based foreground region by setting a pixel to be inspected and determining whether the selected pixel is included in the region-based foreground region, based on peripheral pixels of the selected pixel;
- and
- selecting a final motion region by comparing the pixel-based foreground region and the region-based foreground region.
