manual pixel selection for grow cut segmentation then autosegment based on pixel intensity values within 100 then apply to subsequent slices in matlab

main.m
% Load image
img = imread('my_image.png');

% Display image and allow user to select ROI
roi = roipoly(img);

% Perform grow-cut segmentation based on pixel intensity values within 100 of ROI
bw = imdilate(roi, strel('disk', 5));
bw = growcut(img, bw, 100);

% Apply segmentation to subsequent slices
for i = 2:num_slices
    img = imread(['my_image_', num2str(i), '.png']);
    bw = imdilate(bw, strel('disk', 5));
    bw = growcut(img, bw, 100);
    % do something with the segmented image
