dc.description.abstract |
The history of stereo analysis of images dates back more than
one hundred years, but stereo analysis of image sequences is a fairly recent
subject. Sequences allow time-propagation of results, but also come
with particular characteristics such as being of lower resolution, or with
less contrast. This article discusses the application of belief propagation
(BP), which is widely used for solving various low-level vision problems,
for the stereo analysis of night-vision stereo sequences. For this application
it appears that BP often fails on the original frames for objects with
blurry borders (trees, clouds, . . . ). In this paper, we show that BP leads
to more accurate stereo correspondence results if it is applied on edge
images, where we have decided for the Sobel edge operator, due to its
time efficiency. We present the applied algorithm and illustrate results
(without, or with prior edge processing) on seven, geometrically rectified
night-vision stereo sequences (provided by Daimler AG, Germany). |
