294 Feature Extraction and Image Processing
statistical and combination approaches. Clearly the frequency content of an image will
reflect its texture; we shall start with Fourier. First though we shall consider some of the
required properties of the descriptions.
8.3 Texture description
8.3.1 Performance requirements
The purpose of texture description is to derive some measurements that can be used to
classify a particular texture. As such, there are invariance requirements on the measurements,
as there were for shape description. Actually, the invariance requirements for feature extraction,
namely invariance to position, scale and rotation, can apply equally to texture extraction.
After all texture is a feature, albeit a rather nebulous one as opposed ...
