It is not clear to me exactly what is your goal? Are you trying to convert image pixels into binary bits? If so, you can use dec2bin for that, and bin2dec to get your image back.
I_in = your image...
% encoding image into array of bits
B = dec2bin(I_in);
C = reshape(B',1,numel(B)); % converted into bits
% decoding image from bits
D = reshape(C,size(B,2),size(B,1));
I_out = reshape(bin2dec(D'),size(I_in))

Hello there! I hope you can help me with this question... I'm simulating a Digital Comm System, so i want to transmit an image and for that i converted that image into a bitstream, i used "imbinarize" function and reshape the matrix into a row vector for the "transmission" which function should i use to make the opposite process for the recosntruction of the image? Thanks!

reshape() to reconstruct the image. The remote side will need to know the image size, so either the size will need to be fixed or else you will need to transmit size information.
Note that your process will end up with a black and white image. If you want grey or color then you will need to use something different than imbinarize
