Abstract :
This work aims to compare two segmentation tools that are based on the same multiresolution segmentation algorithm. The main significance of this investigation is to assess the feasibility of the use of a free tool (InterIMAGE) instead of a commercial one (eCognition) but still achieving equivalent results. Samples extracted from an optical image (LANDSAT5/TM) were used to fill the segments of a phantom image, creating 100 repetition of 3 simulated image. The obtained simulated images were then segmented using both tools with several parameter configurations and the results were evaluated through a supervised segmentation quality measure. Results obtained by eCognition are better in all tested cases.
