how to write(save) the output image

Answer 1

If you want to save your plots you could use the print command

 doc print

Eg.

h=figure
plot(1:4)
print(h,'-dbmp','-noui','myFig')    % this saves myFig.bmp in current directory

To save an image you can use imwrite

 doc imwrite

Hi Thomas,

I want to save the output image.

I can able to save an image as output when i write the following code:

im = imread('football.jpg'); % Load a jpeg image

imwrite(im,'news.jpeg');

My project is to acquire a live image using webcam and convert it to frames and store.. I used imsave. But, it is making us to store manually. I need the output to be saved automatically.

Is it possible

You need to describe this better. I've never heard of imsave(). Of course I've heard of imwrite() and it works fine - you just need to supply it the proper numerical array and filename. Why are you not able to supply those, or else what is going wrong when you do?
