% read the image
img = imread('sample.jpg');

% convert to the HSV color space
img_hsv = rgb2hsv(img);

% extract the H (hue) channel, which encodes color information
hue_channel = img_hsv(:,:,1);

% define the red color range in the hue channel (here, red is displayed as yellow because the hue range is circular)
red_range = hue_channel > 0.95 | hue_channel < 0.05;

% apply the color threshold to the image
img_red = img;
img_red(repmat(~red_range, [1 1 3])) = 0;

% display the original and detected images side by side
figure;
subplot(1,2,1); imshow(img); title('Original image');
subplot(1,2,2); imshow(img_red); title('Detected red objects');
