This paper outlines a scheme for image texture recognition using Wavelet transforms. The texture image is decomposed at 3 levels using a 2-D Haar Wavelet and a combined coefficient based on the decomposition matrices is used as a discrimination feature. The combined coefficient is obtained by using standard deviations of the approximation and detail Wavelet coefficients at each of the levels. The proposed scheme is tested on a dataset of 260 images divided into 4 categories, and demonstrates accuracies around 95% which is at par with those reported in extant literature.
