[...]
...Several sub-problems related to floor plan analysis have been investigated, ranging from simple raster to vector conversion [20,34] to the full interpretation of the whole plan [10,26,37] going through intermediate tasks such as symbol recognition [24], symbol spotting in large libraries [11] or room detection and segmentation [2,27]....
[...]
...Since [2] is based on thick, medium, and thin line separation for walls detection, the method is useless in its baseline for textured wall segmentation, as it is the case of TexturedSet, TexturedSet2 and ParallelSet....
[...]
...In addition to that, some of the recently presented works on room detection [2,15,27] assumed that all floor plan images have the same resolution and line thickness....
