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
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 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)
