Perceptually-based Color Assignment
نویسندگان
چکیده
Color assignment is a complex task of incorporating and balancing area configuration, color harmony, and user’s intent. In this paper, we present a novel method for automatic color assignment based on theories of color perception. We define color assignment as an optimization problem with respect to the color relationships as well as the spatial configuration of input segments. We also suggest possible constraints that are suitable for taskspecific purposes and for enhancing visual appeal. Our colorization scheme is useful in many applications such as infographics, computer-aided design, and visual presentation. The user study shows that our method generates perceptually pleasing results over a variety of data sets.

Rotation Invariant Color Texture Classification in Perceptually Uniform Color Spaces
* * * b a L is a perceptually uniform color space and HSV approximately perceptually uniform space for representing color. But commonly used color space is RGB, which is not perceptually uniform. In this work we compare these three-color spaces for rotation invariant color texture classification. The inclusion of color aspects of texture in image processing is increasing rapidly. Gabor wavelets...

متن کاملA New Method for Color Gamut Mapping by Genetic Algorithm
To reproduce an image, it is necessary to map out of gamut colors of the image to destination gamut. It is clear that the best color gamut mapping introduces the perceptually closest image to the original one. In this study, a new color gamut mapping is purposed by the aid of Genetic Algorithm (GA). The color difference between the original and mapped images based on S-LAB formula was chosen as...
متن کاملVisual detection and perceptual independence: assessing color and form.
Visual stimuli are multidimensional. One important perceptual problem is to determine how the dimensions are combined. One important aspect of dimensional combination is whether the dimensions are perceptually independent or perceptually correlated. A new task is presented--the visual detection task--that directly assesses the degree of perceptual correlation between any two dimensions. Two exp...
متن کاملA Histogramm with Perceptually Smooth Color Transition for Image Retrieval
We propose a novel histogram generation technique using the HSV color space. The histogram retains a perceptually smooth color transition that enables us to do a window-based comparison of feature vectors for the purpose of effective retrieval of similar images from very large databases. During retrieval, we use a vector cosine distance measure for the ordering of image feature vectors. This di...
