Color Measurement
One of the key elements in successfully utilizing a textile color matching and quality control system is the accurate and repeatable measurement of the samples being evaluated. Poor technique in sample measurement will greatly diminish the accuracy of the formulas produced by the shade matching software and will provide misleading results from the quality control software. Mistakes in either ar...
متن کاملMeasurement of Color Texture
In computer vision, measurement of image properties such as color or texture is essential. In this paper, we propose a solid framework for the local measurement of texture in color images. We give a physical basis for the integration of the well-known Gabor filters with the measurement of color. Our method implies that the colortexture is measured in the wavelength-Fourier domain. The measureme...
متن کاملMeasurement of Color Invariants
This paper presents the measurement of object reflectance from color images. We exploit the Gaussian scalespace paradigm to define a framework for the robust measurement of object reflectance from color images. Illumination and geometrical invariant properties are derived from a physical reflectance model based on the Kubelka-Munk theory. Imaging conditions are assumed to be white illumination ...
متن کاملColor measurement and discrimination.
Theories of color-difference measurement provide a quantitative means for predicting whether two lights will be discriminable to an average observer. Consider the following color-measurement hypothesis. Suppose that two lights evoke responses from the color channels that we write as vectors, U and U'. The vector difference dU = U - U' is itself a set of channel responses that will result from t...
متن کاملAccurate Color Measurement
In this thesis studies on accurate surface color measurements are considered. Errors in a spectrophotometric measurements are discussed and correction methods introduced. The wavelength interval in a tristimulus integration is considered next. The ASTM weighting functions are tested with a large data set of non fluorescent colors and shown to be useless. The thermochromic effect is also discuss...
