There are more than 350 fl owing waters in Poland with names containing a colour adjective. Etymological propositions mention sometimes various physical attributes such as the colour of the water or of the bottom, or even a possible symbolical usage connected e.g. with the cardinal directions, but most often they limit themselves to citing the literary version of the adjective, and there end their inquiry. The goal of the present paper is to establish to what degree physical attributes can explain the use of colour epithets; and if they cannot, then whether there is any reason to believe that there existed in the past a more elaborate system of colour symbolism.
In their handling of colour, Tibeto-Burman languages of the Himalayan region show multiple lexical similarities to one another as well as apparent influences from more dominant languages such as Hindi, Nepali, Tibetan, and Chinese. As an understudied family, Tibeto-Burman languages also serve as an important site to explore modern colour theory and conceptualisation. Outlier languages in the Tibeto-Burman family that do not appear to follow either traditional or revised versions of Brent Berlin & Paul Kay's theories are of particular significance. This survey provides a systematic review of the existing literature and a baseline of comparative colour terminology for these generally vulnerable and often endangered languages.
Effects of infrared power output and sample mass on drying behaviour, colour parameters, ascorbic acid degradation, rehydration characteristics and some sensory scores of spinach leaves were investigated. Within both of the range of the infrared power outputs, 300–500 W, and sample amounts, 15–60 g, moisture content of the leaves was reduced from 6.0 to 0.1±(0.01) kg water/kg dry base value. It was recorded that drying times of the spinach leaves varied between 3.5–10 min for constant sample amount, and 4–16.5 min for constant power output. Experimental drying data obtained were successfully investigated by using artificial neural network methodology. Some changes were recorded in the quality parameters of the dried leaves, and acceptable sensory scores for the dried leaves were observed in all of the experimental conditions.
The paper is devoted to the analysis of the image of a garnet bracelet in the story of the same name by Aleksandr Kuprin. The grant bracelet is considered as a complex, multidimensional image with intentionally contradictory semantics. This is a kind of amulet of Zheltkov, along with which he gives his life to Princess Vera. Red and yellow garnet stones symbolize the near death of the donor, and the power of his love, and eternal life. The giving of the bracelet at the same time symbolizes the conclusion of a mystical marriage between its owner and Vera Sheina. Complex symbolic meanings arise due to references to various texts and plots, especially the myth of Pluto and Persephone (the parallel is based on the homonymy of garnet-mineral and pomegranate-fruit in Russian). In the symbolis of Kuprin's story, a kinship with the poetics of Russian symbolism is traced.
Present paper is a continuation of works on evaluation of red, green, blue (RGB) to hue, saturation, intensity (HSI) colour space transformation in regard to digital image processing application in optical measurements methods. HSI colour space seems to be the most suitable domain for engineering applications due to its immunity to non-uniform lightning. Previous stages referred to the analysis of various RGB to HSI colour space transformations equivalence and programming platform configuration influence on the algorithms execution. The main purpose of this step is to understand the influence of computer processor architecture on the computing time, since analysis of images requires considerable computer resources. The technical development of computer components is very fast and selection of particular processor architecture can be an advantage for fastening the image analysis and then the measurements results. In this paper the colour space transformation algorithms, their complexity and execution time are discussed. The most common algorithms were compared with the authors own one. Computing time was considered as the main criterion taking into account a technical advancement of two computer processor architectures. It was shown that proposed algorithm was characterized by shorter execution time than in reported previously results.
This paper introduces a new comprehensive procedure for both geometric and colour calibration of structured light system. In order to perform both geometric and colour calibration procedure, a new calibration artifact is proposed. The intrinsic and extrinsic parameters of projector and camera are estimated by using an extended pinhole camera model with a tangential and radial distortion. Camera image plane coordinates are obtained by extracting features from images of a calibration artifact. Projector image plane coordinates are calculated on the basis of continuous phase maps obtained from a fringe pattern phase reconstruction procedure. In order to stereo calibrate camera-projector system, pairs of corresponding image plane points are calculated with subpixel accuracy. In addition, one of three pattern views is used in colour calibration. RGB values of a colour field pattern detected by camera and their reference values are compared. This comparison leads to derivation of a colour transformation matrix. The performance of the proposed method is tested by measuring plane, sphere and distance reference. Also 360 degrees complex object 3D model from a set of measurements is obtained. Residual mean errors for all tests performed are calculated.
