tracking a moving boundary in matlab

main.m
% Load the first image
img = imread('first_frame.jpg');

% Detect the boundary using edge detection
edge_img = edge(img, 'canny');

% Initialize the boundary location
boundary = bwperim(edge_img);

% Display the original image with boundary superimposed
imshow(img)
hold on
visboundaries(boundary, 'Color', 'r');

% Loop through subsequent frames
for i = 2: num_frames
    % Load the next image
    img = imread('frame' + i + '.jpg');
    
    % Detect the boundary using edge detection
    edge_img = edge(img, 'canny');
    
    % Track the boundary movement using optical flow
    flow = opticalFlowLK('NoiseThreshold',0.009);
    flow = estimateFlow(flow, edge_img);
    pts = [x,y];
    [pts, validIdx] = step(opticalFlowLK, edge_img);
    boundary = pts(validIdx, :);
    
    % Display the current image with boundary superimposed
    imshow(img)
    hold on
    visboundaries(boundary, 'Color', 'r');
