I got a blank image as both input and output images when i process the matlab codes in the attached file. And there is no error shown in the command window. What is the reason for this and How can i solve this?

The problem is that your converted your image to a double then applied rgb2gray. When the input is double, rgb2gray is expecting image values between 0 and 1, but your original image has values between 0 to 255 (uint8).
This conversion (to double) step is not necessary to execute rgb2gray.
