-
class
open3d.ml.tf.vis.LabelLUT(label_to_names=None)¶ The class to manage look-up table for assigning colors to labels.
-
class
Label(name, value, color)¶ -
__init__(name, value, color)¶ Initialize self. See help(type(self)) for accurate signature.
-
-
__init__(label_to_names=None)¶ - Parameters
label_to_names – Initialize the colormap with this mapping from labels (int) to class names (str).
-
add_label(name, value, color=None)¶ Adds a label to the table.
Example
The following sample creates a LUT with 3 labels:
lut = ml3d.vis.LabelLUT() lut.add_label('one', 1) lut.add_label('two', 2) lut.add_label('three', 3, [0,0,1]) # use blue for label 'three'
- Parameters
name – The label name as string.
value – The value associated with the label.
color – Optional RGB color. E.g., [0.2, 0.4, 1.0].
-
classmethod
get_colors(name='default', mode=None)¶ Return full list of colors in the lookup table.
- Parameters
name (str) – Name of lookup table colormap. Only ‘default’ is supported.
mode (str) – Colormap mode. May be None (return as is), ‘lightbg” to move the dark colors earlier in the list or ‘darkbg’ to move them later in the list. This will provide better visual discrimination for the earlier classes.
- Returns
List of colors (R, G, B) in the LUT.
