matlab创建多个窗口,Matlab在图像上创建窗口

老派for-Loop方法 –

%%// Outputs that you are interested in are - img, x1 and y1

img = rgb2gray(input_image); %%// Gray level values

x1 = zeros(size(img)); %%// Row values for the maximum pixel in the 16x16 window

y1 = zeros(size(img)); %%// Column values for the maximum pixel in the 16x16 window

for k1= 1:size(img,1)-15

for k2= 1:size(img,2)-15

img1 = img(k1:k1+15,k2:k2+15);

[val,ind1] = max(img1(:));

img(k1+8,k2+8)=val; %%// Store the max grey value into the image

[x1(k1,k2),y1(k1,k2)] = ind2sub([16 16],ind1);

end

end

编辑1：要计算此滑动窗口的平均值,请使用此 –

window_size = 16; %%// Edit this to your window size

wsz = window_size-1;

mp = round(window_size/2);

%%// Outputs that you are interested in are - img, x1 and y1

img = rgb2gray(input_image); %%// Gray level values

x1 = zeros(size(img)); %%// Row values for the maximum pixel in the 16x16 window

y1 = zeros(size(img)); %%// Column values for the maximum pixel in the 16x16 window

img1 = img;

for k1= 1:size(img,1)-wsz

for k2= 1:size(img,2)-wsz

window_data = img(k1:k1+wsz,k2:k2+wsz);

val = round(mean(window_data(:)));

img1(k1+mp,k2+mp)=val; %%// Store the mean grey value into the image

end

end

figure,imshow(img1)

编辑2：

img1 = Z;

for k1= 1:size(Z,1)-wsz

for k2= 1:size(Z,2)-wsz

window_data = Z(k1:k1+wsz,k2:k2+wsz);

val = mean(window_data(:))

if (val~=0)

keyboard;

error('Look, there is a non-zero mean value!');

end

% img1(k1+mp,k2+mp)=val; %%// Store the mean grey value into the image

display(val);

end

end
