How to store every iteration of while loop into array?

favorite_image = imread('matlab project.jpg');

imshow(favorite_image)

sick=favorite_image

resize = favorite_image

counter={} %saving an empty array

while length(resize) > 32

resize = imresize(resize,1/2)

sick = resize

imshow(resize)

sick{counter+1} = resize %trying to store stuff in empty array

end

imshow(resize)

I am trying to put every single image from the resizing in the same array when I try to do it this way, it says that the operator is not supported for operand cell. What am I doing wrong? Thank you!

Hi Riley,

I believe what you are trying to do is create an cell array of images which adds on a new image in each iteration.

In the line

sick{counter+1} = resize %trying to store stuff in empty array

you are trying to add a numerical value to an empty cell type which is not allowed. In order to acheive what you are doing you can refer to the following psuedo code,

favorite_image = imread('image.jpg');
imshow(favorite_image)
resize = favorite_image
dummyresize=favorite_image
numimage=1;
while length(dummyresize) > 32
dummyresize = imresize(dummyresize,1/2)

numimage=numimage+1;

end
counter=cell(1,numimage) %creating a cell array of size number of images
a=1;
while length(resize) > 32
resize = imresize(resize,1/2)
sick = resize
imshow(resize)
counter{a} = resize %store stuff in cell array
a=a+1;
end
imshow(resize)
for i = 1:numimage
    imshow(counter{i})%show all the image saved in counter
end

The above code keeps on adding the new image to the cell array counter.

I hope this solves your query.
