Abstract: | This article presents an adaptive approach to improving the infection algorithm that we have used to solve the dense stereo
matching problem. The algorithm presented here incorporates two different epidemic automata along a single execution of the
infection algorithm. The new algorithm attempts to provide a general behavior of guessing the best correspondence between
a pair of images. Our aim is to provide a new strategy inspired by evolutionary computation, which combines the behaviors
of both automata into a single correspondence problem. The new algorithm will decide which automata will be used based on
the transmission of information and mutation, as well as the attributes, texture, and geometry, of the input images. This
article gives details about how the rules used in the infection algorithm are coded. Finally, we show experiments with a real
stereo pair, as well as with a standard test bed, to show how the infection algorithm works. |
