Create Binary Mask Using an ROI Function

This example shows to create a binary mask using one of the ROI creation functions, such as drawcircle, with the mask creation function createMask.

Read an image into the workspace and display it.

img = imread('pout.tif');
h_im = imshow(img);

Create an ROI on the image using one of the ROI creation functions.

circ = drawcircle('Center',[113,66],'Radius',60);

Create a binary mask from the ROI using createMask. The createMask function returns a binary image the same size as the input image. The pixels inside the ROI are set to 1 and the pixel values everywhere else are set to 0.

BW = createMask(circ);
imshow(BW)
