![]() Image LabelingThe connected components labeling produces as an output an image model IL, with vectorial representation of Labeled Image, similar to the function of image segmentation. The labeling is performed on the active IL, usually over a classified image (image model) or raster related to a thematic image (thematic model). In both cases, you can control the area parameter (in pixels), referring to the input/output Layer, besides the smoothness of lines to be created. The Input Layer can be changed by removing polygons with areas smaller than a given value, substituting the class or color for one in its neighborhood. The Output Layer, where the labeled image will be created, allows the elimination or not of the smaller areas.
Notice that the InfoLayer will be available at the Control Panel after this procedure. The figures below show the labeling of connected components performed over an image model IL, where areas smaller than 40 pixels where eliminated from the Input Layer. The output labeled image kept the lines which involved the deleted polygons. Classified Image (original) Image with deleted areas Output Labeled Image
