Calibrated image appearance reproduction
ACM Transactions on Graphics, 2012Managing the appearance of images across different display environments is a difficult problem, exacerbated by the proliferation of high dynamic range imaging technologies. Tone reproduction is often limited to luminance adjustment and is rarely calibrated against psychophysical data, while color appearance modeling addresses color reproduction in a ...

Image Reproduction with Interactive Graphics
Applied Optics, 1974Software application or development in optical image digital data processing requires a fast, good quality, yet inexpensive hard copy of processed images. To achieve this, a Cambo camera with an f 2.8/150-mm Xenotar lens in a Copal shutter having a Graflok back for 4 x 5 Polaroid type 57 pack-film has been interfaced to an existing Adage, AGT-30 ...

Tone reproduction for realistic images
IEEE Computer Graphics and Applications, 1993Radiosity and other global illumination methods for image synthesis calculate the real world radiance values of a scene instead of the display radiance values that will represent them. Though radiosity and ray tracing methods can compute extremely accurate and wide-ranging scene radiances, modern display devices emit light only in a tiny fixed range ...

The Quality Analysis of Image Reproduction
Journal of Imaging Science and Technology, 2000The objective of image reproduction is, as used here, to reproduce visual information that is available in the original image. Undoubtedly, the colors of the individual pixels contain a huge amount of visual information and therefore the quality of the image reproduction is typically studied in terms of the quality of the color reproduction determined ...

Image preservation through reproduction
Journal of Audiovisual Media in Medicine, 1985Continuing the series of articles on various aspects of image conservation, the author elaborates on one of the concepts mentioned in his introductory paper (JAMM 1984, 7, 87–90) and explores the philosophy and practicality of preservation through faithful successive reproduction which has now become realistic on an infinite scale.

Color Reproduction for Digital Imaging Systems
2006 IEEE International Symposium on Circuits and Systems, 2006This paper presents a new color reproduction approach that combines auto white balance (AWB) and color correction to recover the spectral reflectance properties of the objects in the scene and the spectral power distribution of the incident illuminants. By fully utilizing the calibration result of CCD/CMOS sensors characteristics, the AWB algorithm can

Imaging of the Male Reproductive Tract
Atlas of the Urologic Clinics, 1999Radiologic imaging may often play a critical role in the evaluation and management of patients with male factor infertility. Historically, the role of radiologic imaging was confined to vasography in the diagnosis of obstructive azoospermia. Today, radiologic imaging modalities have three indications in subfertile men.

Optimizing color reproduction of natural images
Color and Imaging Conference, 1998The paper elaborates on understanding, measuring and optimizing perceived color quality of natural images. We introduce a model for optimal color reproduction of natural scenes which is based on the assumption that color quality of natural images is constrained by perceived naturalness and colorfulness of these images.

Tone reproduction of High Dynamic Image
2010 IEEE International Conference on Intelligent Systems and Knowledge Engineering, 2010High Dynamic Range Image (HDRI) is a type of images with wide luminosity levels in real scenes. It is very important to fuse the multiple photographs into a single HDRI. A method that constructs HDRI through recovering response curve of camera imaging system is proposed.

High-Dynamic-Range Image Reproduction Methods
IEEE Transactions on Instrumentation and Measurement, 2006The high dynamic range of illumination may cause serious distortions and problems in the viewing and further processing of digital images. Important information can be hidden in the highly or extremely lowly illuminated parts. This paper deals with the reproduction of such images and introduces two new tone reproduction preprocessing algorithms which ...
