The color of pixels can be represented in different color spaces which respect different properties. Many authors have compared the classification performances reached by these color spaces in order to determine the one which would be the well suited to color texture analysis. However, the synthesis of these works shows that the choice of the color space depends on the considered texture images...

In this paper, we present an effective saliency detection method based on color contrast and similarity distribution information. We define a salient object by measuring its color contrast to surroundings and compactness similarity distribution. In the method, both global and local color contrasts are considered to measure the color distinctiveness, and similarity distribution is used to measur...

In camera-based object recognition and classification, surface color is one of the most important characteristics. However, apparent object color may differ significantly according to the illumination and surface conditions. Such a variation can be an obstacle in utilizing color features. Geusebroek et al.’s color invariants can be a powerful tool for characterizing the object color regardless ...

The application specific paper describes a design approach for digital opto sensors and data acquisition systems. It is based on the Universal Frequency-to-Digital Converter (UFDC-1) working well with any frequency output sensors, for example, lightand color-to-frequency converter from TAOS. Such design approach lets significantly simplify the design process, reduce time to market and productio...

Whereas numerous methods are used for vision systems embedded on robots, only a few use colored region segmentation mainly because of the processing time. In this paper, we propose a real-time (i.e. video rate) color region segmentation followed by a robust color classification and region merging dedicated to various applications such as RoboCup four-legged league or an industrial conveyor whee...

Characterization and estimation of device independent color co-ordinates of scanned or photographic images of through empirical models is a typical issue for commercial desktop scanners and cameras. As a domain of complex problem for optimising suitable color model to evaluate textiles and paints, we investigated the effect of different DPI and device independent color coordinate selection for ...

Disclosed is a method of preparing pigmentary chromium oxide nano particles having 50 percent particle size less than about 100 nm. Preparation of nano chromium (III) oxide is investigated by thermal decomposition method. According to the disclosed method, a substantially dry solid composition of potassium dichromate and carbon active is heated in CO2 atmosphere to a temperature of about 60...
