| Abstract: | This
study addresses problem of classifying rotated, scaled and translated texture
image using two stage log polar quaternion wavelet energy signatures. Sum of
squared distance is employed to classify a set of 38 distinct natural textures
selected from Brodatz album and 48 from Outex texture database. Based on
different testing data sets for images with different orientations scales and
translation, proposed classification scheme using QWT outperforms other
approaches, giving a good classification accuracy and retrieval efficiency
(grey scale, > 85% and color textures, > 83%). |
