Images are generally represented in the RGB color space. This is the
model commonly used for most cameras and for displaying on computer
screens. Nevertheless, the representation of color images using this color space
has some important drawbacks for image analysis. For example, it is a
non-uniform space, that is, measured color differences are not proportional to
the human perception of such differences. On the other hand, HSI color space is
closer to the human color perception and CIE Lab color space has been defined
to be approximately uniform. In this work, the influence of the color space for
color texture characterization is studied by comparing Lab, HSI, and RGB color
spaces. Their effectiveness is analyzed regarding their influence over two
different texture characterization methods: DFT features and co-occurrence
matrices. The results have shown that involving color information into texture
analysis improves the characterization significantly. Moreover, Lab and HSI
color spaces outperform RGB [-]
