Matlab-零填充(2)

Question

有人能帮忙吗？不知道为什么会出错？

赋值在17 padded_image(padding+1:padding+image_size(1)，padding+1:padding+image_size(2)) =图像，==> create_padded_image在9 padded_image = create_padded_image (图像)时的非单例rhs维数大于非单例rhs的下标误差。

function padded_image = create_padded_image(image, padding)  
if nargin < 2         
    % if no padding passed - define it.         
    padding = 5; 
end
if nargin < 1     
    % let's create an image if none is given
    image = imread('GreyScale.bmp');
    padded_image = create_padded_image(image) 

end  
    % what are the image dimensions? 
    image_size = size(image);   
    % allocate zero array of new padded image 
    padded_image = zeros(2*padding + image_size(1), 2*padding + image_size(2));
    % write image into the center of padded image 
    padded_image(padding+1:padding+image_size(1), padding+1:padding+image_size(2)) = image; 
end

试一试

image_size = size(image);
padded_image = zeros(2*padding + image_size(1), 2*padding + image_size(2), size(image,3), class(image));
padded_image(padding+1:padding+image_size(1), padding+1:padding+image_size(2), :) = image;
