一、roipoly

roipoly(img)可以提取掩碼區域，建立掩碼影象。

二、程式碼

clear
jpg = imread('C:\\Program Files\\MATLAB\\R2017a\\toolbox\\images\\imdata\\baby.jpg');

roi = im2uint8(roipoly(jpg));
roi_cmp = bitcmp(roi);
interest = bitand(jpg,roi);
non_interest = bitand(roi_cmp,imdivide(jpg,1.5));
combine = bitor(interest,non_interest);
subplot(2,2,1),imshow(jpg),title('initial')
subplot(2,2,2),imshow(interest),title('interest')
subplot(2,2,3),imshow(non_interest),title('non_interest')
subplot(2,2,4),imshow(combine),title('combine')
