Its OK, but is there any option to check that if a image is captured by webcam is to compare with database that the same image is present there or not and show a message that "Duplicate" ?

The Simple Image Comparison solution tells you the percentage difference. You can have a threshold defined in your program and if difference is less than equal to that threshold then you can flag the image as duplicate.
