    Abstract: A combined statistical and structural approach is presented in this paper for texture representation. A set of tonal primitives (Binary or Gray level based) have been suggested, called Texture Primitives which are of size (3×3). These primitives are basically tested for the presence of texture by conducting a suitable statistical test called Nair’s test. The texture primitives are analogous to texture number as suggested by He and Li Wang. The set of universal primitives are labeled as local descriptor and the frequency of occurrences of these primitives is used as the global descriptor, namely Texture Primitive Spectrum for a given texture image. Since the occurrence of primitives and their placement rules uniquely define a texture image, the primitive spectrum is also unique, for a texture image. The primitive spectrums are presented for a variety of texture images of Brodatz album. These spectrums are shown to be effectively used for texture classification and promising results are obtained.
