We propose and analyze extensions of the Mumford-Shah functional for the color images. Our main motivation is the concept of images as surfaces. We also review most of the relevant theoretical background and computer vision literature.

Effects of pH, temperature, and syrup concentration on color formation in glucose syrups were studied and the shelf life of syrups under various conditions was estimated. Temperatures of 5, 25, and 45 ºC, pH values of 4, 5, and 6 as well as concentrations of 30, 40, 50, 60, 70, and 80 ºBrix were examined. After 26 weeks no significant color changes were observed at 5 ºC. At 45 ºC, color formati...

purpose: to evaluate color vision in patients with type ii diabetes mellitus without diabetic retinopathy and compare the results with those of age- and sex- matched normal individuals. methods: this descriptive, comparative study was conducted on 100 diabetic patients without any sign of retinopathy and 100 age- and sex-matched normal subjects. color vision was evaluated using ishihara and far...

The concept of color temperature is derived from an innate characteristics of the human visual system. It is formulated as a visual feature referring to a kind of perceptual feeling about perceived light. Color temperature has also a physical-based definition, and hence, color temperature of observed scenes and visual objects can be modelled in a mathematical way as a one-parameter characterist...

We propose a video retrieval framework based on a novel combination of spatiograms and the Jensen-Shannon divergence, and validate its performance in two quantitative experiments on TRECVID BBC Rushes data. In the first experiment, color-based methods are tested by grouping redundant shots in an unsupervised clustering. Results of the second experiment show that motion-based spatiograms make a ...

OBJECTIVES This study assessed the color stability of two composites associated with two pulp protectors submitted to accelerated artificial aging (AAA). METHODS 60 test specimens were made with 0.5 mm of protection material (calcium hydroxide - CH or glass ionomer cement - GIC) and 2.5 mm of restoration material (Concept or QuixFil) and divided into 3 groups (n=10) according to the type of p...

one of the most important goals in treating chronic diseases, especially asthma, is the promotion of quality of life (qol). the present study aimed at identifying the effect of educating method on the qol of children, who suffered from asthma.in this clinical trial study, 80 children aged 6-12 years with asthma were divided into two groups: control (face-to-face method) and experimental (visual...
