متن کاملDigital Camera Identification from Images - Estimating False Acceptance Probability
Photo-response non-uniformity noise present in output signals of CCD and CMOS sensors has been used as fingerprint to uniquely identify the source digital camera that took the image. The same fingerprint can establish a link between images according to their common source. In this paper, we review the state-of-the-art identification method and discuss its practical issues. In the camera identif...
متن کاملPixel distribution shifting color correction for digital color images
This paper is concerned with a proposed color correction method called the Pixel Distribution Shifting Color Correction (PDSCC). This method employs a shifting process on the pixel distribution of a color image to correct its white reference point and ensure the white reference point is achromatic. The proposed method has been tested on numerous types of images which include indoor, outdoor, an...
متن کاملPerceptual fidelity measure of digital color images
A digital color image quality metric is proposed in this work based on the characteristics of the human visual system (HVS). Chromatic coordinates are transformed from spectral cone absorption responses to the opponent-color space. The sensitivity thresholds in each of the color space axes are measured and visual masking models are provided and parameterized. Multiple contrasts are computed by ...
متن کاملREPRODUCIBLE REPRODUCTIONS Color , light , and digital images
We believe that our perception of an object reveals its true nature. However, the image is the result of particular lighting conditions, and the physiology of the eye. In this paper we investigate how to characterize an object independent of its environment. Such that two independent measurements yield the same answer, independent of the lighting and the camera. At the most basic level this pro...
