image through keyboard means, for example if we type 'c' 
from keyboard then matlab should take 'cameraman.tif',if 
we type 'f' then matlab should take 'football.jpg' etc; 
and after taking the image the program should use the 
image which we have provided to the program(like here we 
have provided 'cameraman.tif').so what is the command or 
function which will ask us 'which image you want to 
process?' and then we can provide any image of our choice.
