Question

i have problem in converting a matrix of type double to image.iam using imwrite for this but each time, the error is too many input arguments. the matrix has values from 0 to 255 but the type is double. i used imread to open the image, then converted it to binary and then used the command double and tried to convert it back into image. i need the binary form in my fyp and then convert it back to image. how is it possible?
if anyone has a solution, kindly help me out.
thanks!

Use this code:

I = imread('test.jpg');
b = dec2bin(I); % b becomes vector
% some actions with binary vector
du = bin2dec(b);
du = reshape(du,size(I)); % converting vector du to 3d Image array 
imwrite(uint8(du), 'du.jpg'); %save our du to file du.jpg

I = imread('du.jpg'); %test if it saved correctly
imshow(du)
