※ 引述《xysyme (chiamin)》之銘言：
: 怎麼用matlab讀一張圖進來
: 是用 open('T1.JPG') 嗎?
: 又如何把圖中的某一個顏色分類出來阿?
: 謝謝大家m(=_=)m

 兩種方式給你參考。

 %1
 img = imread('onion.png');
 a1 = img(:,:,1);
 a2 = img(:,:,2);
 a3 = img(:,:,3);
 subplot(2,2,1);imshow(img);
 subplot(2,2,2);imshow(a1);
 subplot(2,2,3);imshow(a2);
 subplot(2,2,4);imshow(a3);

 %2
 img = imread('peppers.png');
 a1 = img;a1(:,:,2:3) = 0;
 a2 = img;a2(:,:,[1 3]) = 0;
 a3 = img;a3(:,:,1:2) = 0;
 subplot(2,2,1);imshow(img);
 subplot(2,2,2);imshow(a1);
 subplot(2,2,3);imshow(a2);
 subplot(2,2,4);imshow(a3);
