Reconstruction of missing or damaged portions of images is an ancient practice used extensively in artwork restoration. Recently, a few digital inpainting models based on the use of partial differential equations have been proposed. Unfortunately, these algorithms are computationally expensive, usually taking a few minutes to restore small portions of an image, which makes them inappropriate fo...

BACKGROUND Digital image analysis offers advantages over traditional pathologist visual scoring of immunohistochemistry, although few studies examining the correlation and reproducibility of these methods have been performed in prostate cancer. We evaluated the correlation between digital image analysis (continuous variable data) and pathologist visual scoring (quasi-continuous variable data), ...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract In today's digital age, Digital image forgery becomes a common information falsification trend. This is generally done due to the largely available contemporary editing software and superior digital cameras. Authenticity of images becomes a more im...

Noise is an intrinsic specificity of all forms of imaging, and can be found in various forms in all domains of digital imagery. This paper offers an overall review of digital image noise, from its causes and models to the degradations it suffers along the image acquisition pipeline. We show that by the end of the pipeline, the noise may have widely different characteristics compared to the raw ...

IMAGE STATISTICAL FRAMEWORKS FOR DIGITAL IMAGE FORENSICS by Patchara Sutthiwan The advances of digital cameras, scanners, printers, image editing tools, smartphones, tablet personal computers as well as high-speed networks have made a digital image a conventional medium for visual information. Creation, duplication, distribution, or tampering of such a medium can be easily done, which calls for...

Digital watermarking technique is proposed for copyright protection or ownership identification of digital media, such as audio, image, video, or text. A digital signature or digital watermark is embedded in the host media. The digital watermark is hidden such that it is perceptually and statistically undetectable. This watermark can then be extracted from the host media and used to identify th...

Digital image processing is the use of computer algorithms to perform image processing on digital images. As a subcategory or field of digital signal processing, digital image processing has many advantages and applications. One of the applications of digital image processing is for traffic analysis. In literature survey it is found that traffic analysis can be done by Background Subtraction, b...

With the effective image processing tools, the digital image processing technique can be applied to the virtual restoration of artistic paintings. For the restoration of artistic work, digital image processing technique serves many purposes. This paper presents approach for virtual digital restoration of artistic paintings which are suffering from the breaks or cracks. An approach includes dete...

Image hashing allows compression, enhancement or other signal processing operations on digital images which are usually acceptable manipulations. Whereas, cryptographic hash functions are very sensitive to even single bit changes in image. Image hashing is a sum of important quality features in quantized form. In this paper, we proposed a novel image hashing algorithm for authentication which i...
