The effects of thickness, background color, specular reflection, and surface roughness on the color of five commercial restorative resins were studied by reflection spectrophotometry. As thickness increased, values of luminous reflectance and excitation purity increased for a black background but decreased for a white background. Opacity increased dramatically as thickness increased from 1.3 to...

barrier properties are one of the most important factors in the edible film. in this study, edible mungbean films were prepared containing (0%, 15%, 30%, 45%) concentrations of rosemary aqueous extract. then the effect of rosemary was investigated on colorimetric and barrier properties (water vapor permeability, oxygen permeability). rosemary extract increased the absorption of color in the vis...

This paper proposes a novel method, based on Full Range Autoregressive (FRAR) model with Bayesian approach for color image retrieval. The color image is segmented into various regions according to its structure and nature. The segmented image is modeled to RGB color space. On each region, the model parameters are computed. The model parameters are formed as a feature vector of the image. The Ho...

Color marking of stainless steels as a process is known for sometime but still it has not been used widely in the industry. Some industrial applications have been seen. New MOPA fiber lasers allow independent tuning different laser parameters and the marking process can be optimized for producing colors with better quality and visual appearance. Laser processing of metal surfaces creates an oxi...

This paper presents an approach to multi-object image segmentation based on object motion using Markov Random Fields. To support the information gained from motion and to achieve robustness, several additional visual cues extracted from the image data are integrated. Depth information gained from stereo disparity is included to maintain segmentation in case an segmented object stops moving. Mot...

AIM To determine if Color Doppler myocardial imaging could provide evidence of diastolic dysfunction in patients with hypertension whose pulse-wave Doppler parameters were normal. METHOD The study included 33 patients (mean age 48+/-7.3 years) and a control group of 13 sex- and age-matched healthy individuals. Patients were divided into two groups according to mean blood pressure (BP) values ...

The effect of specular reflection, background color and specimen thickness on the color of four commercial denture resins was studied by reflection spectrophotometry. Higher values of luminous reflectance and excitation purity were obtained with a white than with a black background, whereas dominant wavelength was lowered slightly.

In this paper, we suggest an optimization method of parameters of color image segmentation using evolutionary programming (EP). The objective image is colored papers on the background of varying intensity. And, evaluation methods for segmented images are modiied. Also, an experiment for these images is performed. This EP based parameter optimization method for solving an indoor image segmentati...
