You can use the following code snippet to remove the area of twig from the image of apple:

% Read the input binary image
I = imread("Apple_Binary.png");
imshow(I);
 
% Converting the binary image to 8-bit unsigned integers
I = im2uint8(I);
 
% Interactively draw a polygon and select the area of apple twig as ROI
roi = drawpolygon(gca,"Color","yellow");
 
% Create a mask out of ROI
mask = createMask(roi, I);
% Display the Mask
imshow(mask);
 
% Fill the regions in the input image using the mask image
J = regionfill(I,mask); % J is the output image, with twig removed
imshow(J);
