We propose a method to improve the prediction performance of existing color-difference formulas with additional visual data. The formula is treated as the mean function of a Gaussian process, which is trained with experimentally determined color-discrimination data. Color-difference predictions are calculated using Gaussian process regression (GPR) considering the uncertainty of the visual data...

In the conventional color reproduction based on the colorimetric match for a standard observer, color mismatch can be perceived if the color matching functions of the observer deviate from those of the standard observer; this phenomenon is known as observer metamerism. Recently, multi-primary display, using more than three-primary colors, has attracted attention as a color reproduction media be...

Every year, billions of dollars are spent gambling on the outcomes of the NCAA men’s basketball tournament. The current work examines how individuals make predictions for one of the most popular forms of betting, tournament pools, in which individuals must correctly predict as many games in the tournament as possible. We demonstrate that individuals predict more upsets (i.e., wins by a higher-s...

It is generally accepted that human color matching is trichromatic (requires three primaries) because there are three types of cone, each containing one visual pigment. A color match between two stimulus fields is thought to be determined at the receptor level where the rate of quantum absorption by each of the three cone pigments must be equated to obtain a color match. Since there are three c...

We develop a knowledge-based approach (called PROSP) for protein secondary structure prediction. The knowledge base contains small peptide fragments together with their secondary structural information. A quantitative measure M, called match rate, is defined to measure the amount of structural information that a target protein can extract from the knowledge base. Our experimental results show t...

In this paper, we present a new technique of taking a 3D profile measurement using colored structured lighting projection. A pattern of colored stripes was projected onto an object when taking images with cameras from various angles, and then all possible available match information was provided from the acquired images and database of the projection pattern. A correct match was then obtained f...

Different industries are usually faced with computer color matching as an important problem. The most famous formula which is commonly used for recipe prediction is based on Kubelka-Munk K-M theory. Considering that spectrophotometer’s geometry and its situation influence the measured spectral values, the performance of this method can be affected by the instrument. In the present study, three ...

In this paper, a novel segmentation algorithm for color video sequences using the level set technique is proposed. This algorithm is applied to the problem of automatic face region segmentation in video sequences. Given a target color range training set, a model of that color distribution is formed. An objective function is then defined that seeks the boundaries of any regions in an image that ...

Objectives: To compare shade matching skills of color normal males and females. Material and Methods: A total of 174 dental students of both genders (117 females and 57 males, 20 to 25 years old), with no experience in color matching in dentistry, participated in the study. All recruited students passed the Ishihara color vision test for color deficiency, and matched the colors of eight shade t...
