Variational Principles and Perceptual Color Correction of Digital Images
نویسندگان
چکیده
Variational principles appear in a vast number of scientific disciplines. They often provide a ‘view from above’ which permits to better comprehend and analyse problems. In this paper we show how variational techniques can be used to modelise perceptual color correction of digital images. We will show that the basic human visual phenomenology defines a unique class of functionals whose minimization gives rise to color enhancement. This framework provides a unified home for noticeable models of perceptual color correction, as e.g. Retinex.

Perceptual approach for unsupervised digital color restoration of cinematographic archives
The cinematographic archives represent an important part of our collective memory. We present in this paper some advances in automating the color fading restoration process, especially with regard to the automatic color correction technique. The proposed color correction method is based on the ACE model, an unsupervised color equalization algorithm based on a perceptual approach and inspired by...
متن کاملPerceptual Hashing for Color Images Using Invariant Moments
Image hashing is a new technology in multimedia security. It maps visually identical images to the same or similar short strings called image hashes, and finds applications in image retrieval, image authentication, digital watermarking, image indexing, and image copy detection. This paper presents a perceptual hashing for color images. The input image in RGB color space is firstly converted int...
متن کاملColor scene transform between images using Rosenfeld-Kak histogram matching method
In digital color imaging, it is of interest to transform the color scene of an image to the other. Some attempts have been done in this case using, for example, lαβ color space, principal component analysis and recently histogram rescaling method. In this research, a novel method is proposed based on the Resenfeld and Kak histogram matching algorithm. It is suggested that to transform the color...
متن کاملMultiscale Total Variational Alggorithms for Denoising Natural Color Photos in Digital Photography
As digital photography rapidly replacing the traditional film photography as the photography of choice for all but a few devoted professionals, post image processing of natural color photos such as denoising becomes increasingly an integral part of digital photography. Although many denoising schemes have been designed, almost none specifically target natural color photos. Noise in natural colo...
متن کاملInfluences of reconstruction and attenuation correction in brain SPECT images obtained by the hybrid SPECT/CT device: evaluation with a 3‐dimensional brain phantom
Objective: The aim of this study was to evaluate the influences of reconstruction and attenuation correction on the differences in the radioactivity distributions in 123I brain SPECT obtained by the hybrid SPECT/CT device. Methods: We used the 3-dimensional (3D) brain phantom, which imitates the precise structure of gray mater, white matter and bone regions. It was filled with 123I solution (20...
