Description

Like shape_histo_allshape_histo_allShapeHistoAllShapeHistoAllShapeHistoAllshape_histo_all the operator shape_histo_pointshape_histo_pointShapeHistoPointShapeHistoPointShapeHistoPointshape_histo_point carries out 255 threshold value operations within RegionRegionRegionRegionregionregion with the gray values of ImageImageImageImageimageimage. Contrary to shape_histo_allshape_histo_allShapeHistoAllShapeHistoAllShapeHistoAllshape_histo_all only the segmented region containing the pixel (RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn) is taken into account here. The entry i in the histogram then corresponds to the number of holes of this region segmented with the threshold i (FeatureFeatureFeatureFeaturefeaturefeature = 'holes'"holes""holes""holes""holes""holes") or the feature value of the region (FeatureFeatureFeatureFeaturefeaturefeature = 'convexity'"convexity""convexity""convexity""convexity""convexity", 'compactness'"compactness""compactness""compactness""compactness""compactness", 'ansisometry'"ansisometry""ansisometry""ansisometry""ansisometry""ansisometry"), respectively.

Attention

Note that the operator shape_histo_pointshape_histo_pointShapeHistoPointShapeHistoPointShapeHistoPointshape_histo_point only considers the given RegionRegionRegionRegionregionregion and ignores any previously set domain of the input image ImageImageImageImageimageimage.

Result

The operator shape_histo_pointshape_histo_pointShapeHistoPointShapeHistoPointShapeHistoPointshape_histo_point returns the value TRUE if an image with defined gray values is entered. The behavior in case of empty input (no input images available) is set via the operator set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>), the behavior in case of empty region is set via set_system(::'empty_region_result',<Result>:)set_system("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)set_system("empty_region_result",<Result>). If necessary an exception is raised.
