SNOW PARTICLE ELIMINATION
I devised a new method that removes snow flakes from successive
images by surveillance camera. Distant surveillance by TV camera is often used for
traffic obsevation, security, millitary defence systems. However,
observation is hindered due to snowfall in winter. If this can be removed
from a scene, observation becomes easy.
Snow particle elimination utilizes the existence probability of a snow
particle on a pixel. The following examples show cases of light and
heavy snowfall. Click the items and you can see them.
Note that you need MPEG plug-in to see the movies.
