摘要：
A new energy-based method for motion estimation of opaque or transparent objects is described, which uses a reduced number of spatio-temporal Gabor filters. This method is based on the simplifying hypothesis of additive transparency and it copes very well with two specific cases: transparent objects in motion over a fixed background, or over a background moving at the same speed but going in opposite directions.
