Digital image processing remains a challenging domain of programming. All digital images contain some degree of noise. Often times this noise is introduced by the camera when a picture is taken. Image denoising algorithms attempt to remove this noise from the image. In this paper the method for image denoising based on the nonlocal means (NL-means) algorithm has been implemented and results hav...

Undoubtedly, we are living in era of digital information and technology. In this revolutionized world of digital information, we are exposed to a remarkable array of visual imagery. With sophisticated image editing tools and software‟s, it is very easy to manipulate and temper the digital images, thereby questioning the trustworthiness of it. This paper presents a method based on a statistical ...

With the advancements in the field of digital image processing during the last decade, digital image data hiding techniques such as watermarking, Steganography have gained wide popularity. Digital image watermarking techniques hide a small amount of data into a digital image which, later can be retrieved using some specific retrieval algorithms to prove the copyright of a piece of digital infor...

We present a technique to improve embedding capacity of Image using digital logic in this paper. We have applied digital logic operations on two equal halves of an image row to derive the hidden information. We have also compared the change in image using proposed technique and digital logic gate technique. Change in Image using proposed technique is half or more than that of logic gate techniq...

Use of digital imaging within all of the medical imaging modalities and methods provides many advantages and values to the practice of clinical medicine. However, the use of digital technology, digital image structure, and the ability to process digital image data in many ways add additional complexity to many imaging procedures. All medical imaging professionals, including radiologists, techno...

Digital image watermarking is one of the most widely used techniques for protection of ownership rights of digital images. Its commercial applications range from copyright protection to digital rights management. However, although there have been numerous new proposed digital image watermarking techniques, most are not sufficiently robust against watermark attacks. With the main objective of fi...

Nowadays, digital image processing is the most common form of image processing. Digital image processing makes it possible to enhance image features of interest while attenuating detail irrelevant to a given application, and then extract useful information about the scene from the enhanced image. For instance, digital cameras usually include dedicated digital image processing chips in order to ...

The digital revolution in digital image processing has made it possible to create, manipulate and transmit digital images in a simple and fast manner. The adverse affect of this is that the same image processing techniques can be used by hackers to tamper with any image and use it illegally. This has made digital image safety and integrity the top prioritized issue in today’s information explos...
