image = imread('20230913q.jpg'); 
[height, width, ~] = size(image); 
crop_width = floor(width / 2); 
crop_height = floor(height / 2); 
cropped_image = image(1:crop_height, crop_width+1:width, :); 
imshow(cropped_image); 
% 儲存圖片的路徑和檔名 
save_path = fullfile('C:', 'Users', 'Administrator', 'Desktop', 'cropped_image.jpg'); 
% 儲存裁剪後的圖片
 imwrite(cropped_image, save_path); 
function avg = image_average(img)
% 計算一張圖片色階 0-12 的平均值 
% 讀取圖片
 img = imread('cropped_image.jpg'); 
% 轉換圖片色階 
img = im2uint8(img); img = img / 12; 
% 計算平均值
 avg = mean(img(:)); 
end
