Image Tampering Detection For Forensics Applications
Image Tampering Detection For Forensics Applications Jessie Yu-Feng Hsu The rapid growth of image editing softwares has given rise to large amounts of doctored images circulating in our daily lives, generating a great demand for automatic forgery detection algorithms in order to determine the authenticity of a candidate image in a timely fashion. A good forgery detection algorithm should be pas...
متن کاملImage Analysis Algorithms for Feature Extraction in Eye Fundus Images
Retinal images are widely used for diagnostic purposes by ophthalmologists. Therefore, these images are suitable for digital image analysis for their visual enhancement and pathological risk or damage detection. Here, we implement a luminosity and contrast enhancement technique based on domain knowledge. We also review and analyze a previous approach in optic nerve head segmentation to extend i...
متن کاملA Survey of Passive Image Tampering Detection
Digital images can be easily tampered with image editing tools. The detection of tampering operations is of great importance. Passive digital image tampering detection aims at verifying the authenticity of digital images without any a prior knowledge on the original images. There are various methods proposed in this filed in recent years. In this paper, we present an overview of these methods i...
متن کاملA hybrid evolutionary algorithm for feature and ensemble selection in image tampering detection
The detection of the presence of tampered images is of significant importance in digital forensics. The problem with image tampering detection is the vast number of features that are currently available in the literature. It is very challenging to determine the best features to correctly characterise these images. This paper proposes a hybrid evolutionary framework to perform a quantitative stu...
متن کاملDetection of Tampering in Image Using Watermarking
In the last few years there is a tremendous development in the area of high quality digital camera technology. So our life is full of the use of these digital images. However now a days there are lot of software (for example Photoshop, Photoscape, Photoplus and Picasa etc.) that can be used to modify these digital image. Therefore we cannot use these images as a proof or evidence. Therefore det...
