A Color Image Classification by Means of Image Transformations

We have previously studied the approaches which permit to associate a texture to an image, and some properties of such transformations. To do so, we use image transformations which act on the pixels of the original image. Some of these transformations have the following property: they statistically mix in a very homogeneous way the pixels of the image. We say that such a transformation is a Quasi-Mixing Transformation (or QM-transformation for short).

For an image, with the use of a QM-transformation we obtain a locally very homogeneous spatial representation of this image (which was previously not homogeneous). This representation appears to be a texture. It is possible to define criteria which permit to quantify the local homogeneity degree of this texture in order, for example, to extract some statistical attributes from a reduced part of the image.

We show that the statistical model of the texture that we obtain allows to define a representation space in order to discriminate the texture classes and thus the colour images.

More about this publication?
  • Started in 2002 and merged with the Color and Imaging Conference (CIC) in 2014, CGIV covered a wide range of topics related to colour and visual information, including color science, computational color, color in computer graphics, color reproduction, volor vision/psychophysics, color image quality, color image processing, and multispectral color science. Drawing papers from researchers, scientists, and engineers worldwide, DGIV offered attendees a unique experience to share with colleagues in industry and academic, and on national and international standards committees. Held every year in Europe, DGIV papers were more academic in their focus and had high student participation rates.
