• plotLAB(output, draw_polygon=True, marker='o')
  • input the model output results（LAB points，L = 50）
  • draw the polygon by ConvexHull in CIELAB 3D space
  • using gradient lines
  • plot the points in CIELAB 3D space
  • change the marker in situation
• convert_colors(color_codes, to_lab=True)
  • input the color_codes（or color charts）like this:

  ['#424B54', '#93A8AC', '#FFFFFF', '#E2B4BD', '#9B6A6C']
  

  • covert it into RGB or LAB numpy array

• plot_lab_plane(ax, L=50, a_range=(-128, 127, 100), b_range=(-128, 127, 100))
  • plot the surface（e.g. L=50）
• set_lab_color_space(ax)
  • sets the CIELAB color space for a given 3D axis object
