Abstract
An approach for computer perception of outdoor scenes is
presented. The approach is based on integrating information extracted
from thermal images and visual images, which provides information not
available by processing either type of image alone. The thermal image is
analyzed to provide estimates of surface temperature. The visual image
provides surface absorptivity and relative orientation. These parameters
are used together to provide estimates of heat fluxes at the surfaces of
viewed objects. The thermal behavior of scene objects is described in
terms of surface heat fluxes. Features based on estimated values of
surface heat fluxes are shown to be more meaningful and specific in
distinguishing scene components
