Measurement of Color Texture
Hoang, Jan‐Mark Geusebroek · 2002
In computer vision, measurement of image properties such as color or texture is essential. However, existing methods for measuring color and texture in combination are not well-defined neither from a measurement theoretical basis nor from a physical point of view. 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 color-texture is measured in the wavelength-Fourier domain. The measurment filter in this domain boils down to a 3D Gaussian, representing a Gabor-Gaussian in the spatial-color domain. We apply a simple segmentation algorithm to illustrate the performance of our proposed color-texture measurement. The derived color-texture filter is demonstrated to be accurate in capturing texture statistics. In addition, the method is compatible with the measurement of grey-value texture.
