Image monitoring apparatus for estimating size of singleton, and method therefor

摘要

An image monitoring apparatus includes a foreground/background separator generating a foreground image by removing background pixels exhibiting no movement from pixels in an image and separating foreground pixels representing pixels of a moving object from the pixels; a foreground object information generator generating foreground object information containing a coordinate value of each of one or more foreground objects included in the foreground image and the number of pixels of the foreground objects; an clustering unit clustering the foreground object information into a plurality of groups; a singleton information detector determining at least one group from the plurality of groups as a group of singletons, and detecting singleton information on the singletons; and a singleton estimation calculator estimating a predetermined area calculation function using the singleton information and calculate at least one of estimates with respect to an area, a width and a height of each of the singletons.

1. An image monitoring apparatus, comprising:
a foreground/background separator configured to generate a foreground image by removing background pixels exhibiting no movement from pixels in an image and separating foreground pixels representing pixels of a moving object from the pixels in the image; a foreground object information generator configured to generate foreground object information containing (i) a coordinate value of each of one or more foreground objects included in the foreground image and (ii) the number of pixels of the foreground objects; a clustering unit configured to cluster the foreground object information into a plurality of groups; a singleton information detector configured to
determine at least one group from the plurality of groups as a group of singletons anddetect singleton information on the singletons; and a singleton estimation calculator configured to
estimate a predetermined area calculation function using the singleton information andcalculate at least one of estimates with respect to an area, a width and a height of each of the singletons.
