The goal is to obtain a disparity map as a previous step for determining distances to the trees and then the volume of wood in the imaged area. The interest is focused on the trunks of the trees. Because of the irregular distribution of the trunks, the most suitable features are the pixels. A set of six attributes is used for establishing the matching between the pixels in both images of the stereo pair. The final decision about the matched pixels is taken by combining the attributes. Two combined strategies are proposed: the Sugeno Fuzzy Integral and the Dempster-Shafer theory. The combined strategies, applied to our specific stereo vision matching problem, make the main finding of the paper. In both, the combination is based on the application of three well known matching constraints. The proposed approaches are compared among them and favourably against the usage of simple features. eng Combination of attributes in stereovision matching for fish-eye lenses in forest analysis book part URL https://docta.ucm.es/bitstreams/3bc62787-6b06-47a8-8535-a3b1cc406567/download File MD5 796bc1e08ecba99b6c1084c0ecdefd53 341501 application/pdf cruzgarcia14.pdf URL https://docta.ucm.es/bitstreams/76d5c972-8989-4d54-8e0e-9638603c2a08/download File MD5 1917531e136195478eea3608f716eb79 43550 text/plain cruzgarcia14.pdf.txt
