WhiteBalance¶

class controllers.WhiteBalance¶

Bases: handle

WHITEBALANCE - Controller for the White Balance correction dialog.

Corrects white balance of RGB images using MATLAB’s chromadapt function. The white point can be detected from selection/mask areas, or specified manually.

Launch as GUI tool:

obj.mibController.startController('controllers.WhiteBalance');

Launch in batch mode:

BatchOpt.PickedRegion = {'ManualValue'};
BatchOpt.ManualWhiteColor = '200 190 180';
obj.mibController.startController('controllers.WhiteBalance', [], BatchOpt);

Trigger return of possible options:

obj.mibController.startController('controllers.WhiteBalance', [], NaN);

Constructor Summary

WhiteBalance(mibModel, varargin)¶

WHITEBALANCE - Constructor.

Syntax:

obj = WhiteBalance(mibModel)
obj = WhiteBalance(mibModel, [], BatchOpt)

Property Summary

BatchOpt¶

cell array of listener handles

listener¶

handle to main MIB figure (used as parent for dialogs)

mibGUI¶

handle to the view (views.WhiteBalanceGUI)

mibModel¶

view¶

handle to MibModel

Method Summary

static ViewListner_Callback2(~, evnt)¶
