in this study the factors controlling the software colorimetry (photoshop), including illumination (direct and indirect), image background (white and black), camera settings (zoom, light, resolution and environmental conditions) and the conversion equations of r, g, b images to l *, a *, b *, compared with the results of the device were investigated and optimized. the results showed that the fa...

It has been well known since the earliest days of color photography that color-balance in general, and facial reproduction (flesh tones) in particular, are of dominant interest to the consumer, and significant research resources have been expended in satisfying this need. The general problem is a difficult one, spanning the factors that govern perception and personal preference, the physics and...

Light field photography has been studied thoroughly in recent years. One of its drawbacks is the need for multilens in the imaging. To compensate that, compressed light field photography has been proposed to tackle the tradeoffs between the spatial and angular resolutions. It obtains using only one lens, a compressed version of the regular multi-lens system. The acquisition system consists of a...

Abstract The growing importance of publishing art collections online has led to increasingly strict tolerances on digital photography objects. There are two internationally recognized sets guidelines for creating high-quality images, Metamorfoze and FADGI. These require using standardized color patches in museal photography. X-Rite ColorChecker SG chart with 140 is often used. Recent studies sh...

In this paper we present (b, s)-BCSL, a new coded structured light method for 3D photography. It employs a sequence of complementary color stripe patterns to define correspondences within a camera/projector shape acquisition system. Unique codes are associated with the boundaries of successive stripes in time. The use of color fully exploits current imaging hardware and makes possible an effect...

OBJECTIVE To compare off-the-shelf digital imaging equipment with a standard single lens reflex 35-mm endoscopic camera in a busy pediatric ears, nose, and throat setting. DESIGN Two digital cameras with an endoscope adapter and a step-down ring were evaluated to obtain optimal settings for digital endoscopic photography. The equipment was used in various clinical and surgical settings to inc...

The color complementation assay (CCA) is a method of allele-specific DNA amplification by which competitive priming and extension of fluorescently labeled oligonucleotide primers determine the color of DNA amplification product. This diagnostic method precludes the need for radioisotopes, electrophoresis, and multiple high-stringency reaction conditions. The multiplicity of mutant globin genes ...

Classical ghost imaging has received considerable attention in recent years because of its remarkable ability to image a scene without direct observation by a light-detecting imaging device. In this article, we show that this imaging process is actually a realization of a paradigm known as dual photography, which has been shown to produce full-color dual (ghost) images of 3D objects with comple...

The paper presents novel techniques based on the Coloroid color system which hitherto has not been applied to gamut mapping. The introduced methods described are hue preserving and use three gravity centers in a huedependent way. Two of the gravity centers are shifted toward the direction of ‘negative saturation’, and can be used for regions of bright and dark colors, while a third gravity cent...
