描述
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.
注意
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。
