Perceptual fidelity measure of digital color images
نویسندگان
چکیده
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 the wavelet coeecients in their corresponding resolutions. The new objective error measure is deened as the aggregate contrast mismatch between the original and compressed images. Experimental results are given to show the its consistency with human observation experience and subjective ranking.

In this paper, an SVD-based perceptual fidelity metric is reviewed and used in the context of objective quantification of image watermarking fidelity for two stateof-the-art Image Adaptive SVD-based Watermarking Schemes. The proposed metric makes use of a Human Visual System perceptual model in the wavelet domain. The robustness of the watermarking schemes against JPEG compression and resizing ...
متن کاملVariational Principles and Perceptual Color Correction of Digital Images
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 minimiza...
متن کاملComparative analysis of color architectures for image sensors
We have developed a software simulator to create physical models of a scene, compute camera responses, render the camera images and to measure the perceptual color errors (CIELAB) between the scene and rendered images. The simulator can be used to measure color reproduction errors and analyze the contributions of different sources to the error. We compare three color architectures for digital c...
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 کاملColor image fidelity metrics evaluated using image distortion maps
Several color image delity metrics are evaluated by comparing the metric predictions to empirical measurements. Subjects examined image pairs consisting of an original and a reproduction. They marked locations on the reproduction that differed detectably from the original. We refer to the distribution of error marks by the subjects as image distortion maps. The empirically obtained image distor...
