Binary mask drawing GUI

GUI for drawing a binary mask on top of a 2D grayscale image.

% Syntax:
>> make_mask_fcn_v2(); %no inputs, plots the 'peaks' image for example purposes
>> make_mask_fcn_v2( user_supplied_2D_image ); %user inputs their own 2D grayscale image
The GUI allows for drawing a binary mask on top of a 2D grayscale image. It is intended for image processing applications where manual mask-making is needed.

There is a demo video included in the attached zip file showing the basic operation of the GUI.

The GUI features undo/redo, manual drawing with selectable brush types (circle, square, rod, etc.), thresholding, imfreehand() drawing, morphological erosion/dialation, and selectable mask overlay colors and transparency.

When the user is finished drawing, the mask can be saved to the workspace using the lower left button in the GUI.

Most of the development was done using Matlab R2015a (linux), but it has been briefly tested on earlier versions.
