Clinicians are constantly challenged with matching one or two incisors to the remaining natural teeth because of the multidimensional properties of color and shape. Single-shade restorations will not adequately match the natural tooth structure and, therefore, will not satisfy most patient expectations. This article describes the steps involved in treatment planning, treatment, laboratory commu...

Since there has been a strong demand from industry to have an efficient way of managing color image quality presented in different media, by specifically investigating partly changed complex images, this article proposed a revision to existing CIE color difference model which cannot give a proper color difference assessment on partly changed complex images. The key method applied is to find out...

AIM To improve the 7-plex system to predict eye and skin color by increasing precision and detailed phenotypic descriptions. METHODS Analysis of an eighth single nucleotide polymorphism (SNP), rs12896399 (SLC24A4), showed a statistically significant association with human eye color (P=0.007) but a rather poor strength of agreement (κ=0.063). This SNP was added to the 7-plex system (rs12913832...

We present a color analysis of the galaxy populations of candidate clusters of galaxies from the Palomar Distant Cluster Survey (Postman et al. 1996). The survey was conducted in two broad band filters that closely match V and I and contains a total of 79 candidate clusters of galaxies, covering an estimated redshift range 0.2 < ∼ z < ∼ 1.2. We examine the color evolution in the 57 richest clus...

In this paper, we propose a method to predict tertiary structure of an RNA sequence. Our prediction method would first find the secondary structure of the given RNA sequence. We then use the relaxation method to predict the 3-space structure of it. Experimental results show that our method is quite feasible. We tested our approach on 731 RNA’s. 179 of them got a complete match, 391 of them got ...

Cricket is a popular sport played by 16 countries, is the second most watched sport in the world after soccer, and enjoys a multi-million dollar industry. There is tremendous interest in simulating cricket and more importantly in predicting the outcome of games, particularly in their one-day international format. The complex rules governing the game, along with the numerous natural parameters a...

In this paper we propose a criterion for uncertainty evaluation in a color quality control. In a joint project between two laboratories of the Faculty of Engineering in Florence we study a PC-CCD system, called Textile Color Match (TCM) for the digital acquisition of the colorimetric coordinates of a wool sample. One of the main result is the achievement of a threshold of tolerance for the repr...

Since 1994 GE Plastics has employed a case-based reasoning tool that determines color formulas which match requested colors. This tool, called FormTool, has saved GE millions of dollars in productivity and material (i.e. colorant) costs. The technology developed in FormTool has been used to create an on-line color selection tool for our customers called ColorXpress Select. A customer innovation...

This paper presents an algorithm for the detection and tracking of moving objects based on color and texture analysis for real time processing. Our goal is to study human interaction by tracking people and objects. The object detection algorithm is based on color histograms and iteratively divided interest regions for motion detection. The tracking algorithm is based on correlograms which combi...

Similarity of color histograms is an important cue for detecting colored objects in complex scenes. It is employed in several applications such as image retrieval, object detection, tracking etc. Focussed color intersection e ciently matches the model against parts of the scene using histogram intersection. We propose an upper bound pruning technique which increases the e ciency of searching fo...
