how to classify images from a webcam in matlab in matlab

main.m
% Create a webcam object
cam = webcam;

% Set up the image processing and machine learning parameters
preprocessMethod = 'contrast'; % Example, you can change this to suit your requirements
featureMethod = 'SURF'; % Example, you can change this to suit your requirements
classifierType = 'svm'; % Example, you can change this to suit your requirements

% Create an image datastore with labeled datasets
imds = imageDatastore('path/to/labeled/images', 'IncludeSubfolders', true, 'LabelSource', 'foldernames');

% Preprocess the images
imds = preprocessImages(imds, preprocessMethod);

% Extract features from the images
features = extractFeatures(imds, featureMethod);

% Train the classifier using the features and labels
classifier = trainClassifier(features, imds.Labels, classifierType);

% Start processing the images from the webcam
while true
    % Capture an image from the webcam
    img = snapshot(cam);
    
    % Preprocess the image
    img = preprocessImage(img, preprocessMethod);
    
    % Extract features from the image
    features = extractFeatures(img, featureMethod);
    
    % Classify the image using the trained classifier
    label = classifyImage(features, classifier);
    
    % Display the image and the predicted label
    imshow(img);
    title(strcat('Predicted Label:', label));
end

% Clean up the webcam object
