Abstract :

Computer graphics field is rapidly growing to the point where human subjects is facing difficulty distinguishing photorealistic computer generated images (PRCG) and photographic images (PIM). In 21th century the computer animation has reached to peak point where images can be manipulated. In other situations, it is highly necessary to distinguish between PRCG and PIM. In legal situation, most of the time as evidence many photographs are used. It must to distinguish the image authentic or forge. If it is forged then identify the region.  In this dissertation, new technique is using for image authentication and detecting forged region. It is also become important to develop method for distinguishing between actual photographs from digital camera and computer generated images. For such technique color filter array is using with demosaicing algorithm. In which the image from digital camera contains traces of resampling. Presence of demosaicing is the important key because in estimation of the actual demosaicing parameter is not required. It shows the application for distinguishing between PRCG and PIM and for accurately localizing forged region within digital camera images.
