imread of an image will gives pixel values in the command window.. can we regenerate the same image from the pixel value?

Seems like a rather odd question from a university MATLAB course instructor ( http://www.mathworks.com/matlabcentral/answers/62600#comment_127978). Certainly you already know that imread() does not necessarily give the pixel values in the command window, unless you leave off the trailing semicolon. And you already know that an image is an array of numbers and that there are different types of images (uint8, double, color, indexed). So I'm not sure what to tell you that you don't already know.
ok ImageAnalyst. Apart from course instructor, what creative things can be done using MATLAB. I have seen some codings like indian flag, heart beating, man and hen fight... Is there any possibility to develop any handheld electronic game devices, which can use any MATLAB application.. it is not mandatory to install matlab software in that system...
i had a discussion with a programmer who works with google. he works with identification of spam mails. I asked is it possible to use MATLAB to identify spam... I would be happy if you explain this concept.
MATLAB is Turing Complete. You can program anything that does not require special hardware.
Some languages are better suited for some tasks than for others.
Direct link to this answer:
imagedata = imread('YourImage.jpg');
imwrite(imagedata, 'YourNewImage.tif'); %can even change the image type
imread can give values like [156 176 187...]..... does the same image is regenerated if i try imwrite([156 176 187...]...
imwrite(uint8([156 176 187...]...)
If you used [156 176 187...] then the data class would be "double" (because that is the default for MATLAB), and that would be a problem, as MATLAB assumes that "double" values should have a range of 0 to 1 for images.
Opportunities for recent engineering grads.
