Open Access Image Manipulation Detection Using Sensor Linear Pattern

(PDF 2,833.4 kb)
In this work, we introduce a new method for localizing image manipulations in a single digital image, such as identifying added, removed (spliced or in-painted), or deformed objects. The method utilizes the so-called Linear Pattern (LP) of digital images as a global template whose integrity can be assessed in a localized manner. The consistency of the linear pattern estimated from the image noise residual is evaluated in overlapping blocks of pixels. The manipulated region is identified by the lack of similarity in terms of the correlation coefficient computed between the power spectral density (PSD) of the LP in that region and the PSD averaged over the entire image. The method is potentially applicable to all images of sufficient resolution as long as the LP in the unmodified parts of the image has different spectral properties from that in the tampered area. No side information, such as the EXIF header or the camera model, is needed to make the method work. Experiments show the capability and limitations of the proposed method, which is robust to mild JPEG compression.

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
