Consistency of color representation in smart phones

Journal of the Optical Society of America A, 2016
One of the barriers to the construction of consistent computer-based color vision tests has been the variety of monitors and computers. Consistency of color on a variety of screens has necessitated calibration of each setup individually. Color vision examination with a carefully controlled display has, as a consequence, been a laboratory rather than a ...

Temporal-Consistency-Aware Video Color Transfer

2021
This paper proposes a new temporal-consistency-aware color transfer method based on quaternion distance metric. Compared with the state-of-the-art methods, our method can keep the temporal consistency and better reduce the artifacts. Firstly, keyframes are extracted from the source video and transfer the color from the reference image through soft ...

A histogram-based color consistency test for voxel coloring

Object recognition supported by user interaction for service robots, 2003
Voxel coloring has become a popular technique for reconstructing a 3D scene from a set of 2D images. While many different variants of this technique exist, all rely on a test to determine if each voxel is projecting to regions of consistent color in all views of that voxel.

Consistency Verification using Data Coloring

2010
Today, the number of functional errors escaping design verification and released into final silicon is growing, due to the increasing complexity of microprocessor systems and the shrinking production schedules of their development. The recent, widespread adoption of multi-core processor architectures is exacerbating the problem, due to the variable ...

Color consistence improvement in LED packages

2012 14th International Conference on Electronic Materials and Packaging (EMAP), 2012
This paper studies the processing parameters in LED package manufacturing which leads to poor color consistence in the LED packages. With 4 process parameters including die color co-ordinate, dispensing idle time, curing idle time and curing temperature, the critical parameters in affecting the LED package color quality has been investigated by design ...

Optimizing color consistency in photo collections

ACM Transactions on Graphics, 2013
With dozens or even hundreds of photos in today's digital photo albums, editing an entire album can be a daunting task. Existing automatic tools operate on individual photos without ensuring consistency of appearance between photographs that share content. In this paper, we present a new method for consistent editing of photo collections.

Achieving consistent color and grayscale presentation on medial color displays

SPIE Proceedings, 2008
Color displays are increasingly used for medical imaging, replacing the traditional monochrome displays in radiology for multi-modality applications, 3D representation applications, etc. Color displays are also used increasingly because of wide spread application of Tele-Medicine, Tele-Dermatology and Digital Pathology.

Color Consistency Reliability of LED Systems

2012
LEDs are devices with inherent variability, which cause luminaire manufacturers a challenge to guarantee a color point, as the base component needs to be selected and carefully checked to ensure that the specification is reached. In this chapter, we propose a method to embrace this variability by using standard linear optimization algorithms and ...

Color-consistent LED modules for general lighting

SPIE Proceedings, 2009
During the last few decades the efficacy and luminous flux of LEDs have developed fast. Also the color quality of white LEDs and LED illumination systems has improved considerably. Thanks to the performance improvements and the continuously declining cost per lumen, it is now possible to create LED lighting systems with high luminous fluxes that can

Guided color consistency optimization for image mosaicking

ISPRS Journal of Photogrammetry and Remote Sensing, 2018
Abstract This paper studies the problem of color consistency correction for sequential images with diverse color characteristics. Existing algorithms try to adjust all images to minimize color differences among images under a unified energy framework, however, the results are prone to presenting a consistent but unnatural appearance when the color ...
