Invariant texture analysis based on attributes of texture elements

A texture can be characterised by the histograms of its texture element´s (texel) attributes. With affine transformations, some texel attributes change but the histogram of all attributes undergoes changes. In this paper, a method to convert the attribute histogram into an invariant histogram is proposed. The invariant histogram shows a higher correlation between the images of same texture than that of with images of different textures. This histogram is useful in characterising textures invariant of scaling and rotation. Experimental results of texture characterisation and recognition using invariant intensity (average texel intensity) histogram are presented
