....vary smoothly in their local neighborhood Con The other GLCM based measures we use for our texture analysis are the Inverse Difference Moment, Mean, Entropy, Sum Entropy, Difference Entropy, Difference Variance, Correlation, Shade, and Prominence. These features are described in [3] 16] [30]. Note that the directionality of a texture can be measured by comparing the values obtained for a number of the above measures as is changed.

For further discussion of these GLCM measures (see [3] 16] [30]) 3) Fractal Dimension (FD) Measures: The underlying assumption for the use of the fractal dimension for texture classification and segmentation is that images or parts of images are self similar at some scale. Various methods that estimate the FD of an image have been suggested. ....

.... [8] 12] and local linear transforms [13] 16] Recently, some modern methods have been developed, such as multichannel methods, multiresolution analysis, Gabor filters, and the wavelet transform [17] 27] Many of these approaches have provided good results in different fields of application [3], 4] 8] 9] but a large number of them have shown very low classification rate (or could not be implemented at all) when texture samples are of small dimensions [28] 29] Texture characterization of the myocardial tissue is not an easy task to perform, due to several reasons. First, it is ....
....about the primitive orientation and texture directionality. VI. COMPARISON WITH OTHER TRANSFORM BASED METHODS We have compared the wavelet image extension technique with other transform based and filtering based methods such as Laws texture energy measures [13] Fourier power spectrum measures [3], 9] and the pyramid structured wavelet transform [22] 26] For this comparison we have used following texture measures: L5, S5, R5, E5, and W5 masks for Laws texture energy measures [9] 13] ring and wedge statistics derived from the Fourier power spectrum [3] 9] calculated for the ....

....error not being a function only of the features but also of the choice of the classifier. The figure of merit approach has the advantage that it does not depend on any classification scheme, and in addition, error is bounded by the figure of merit for some classif iers. Weszka et al.[223] compared texture measures for terrain classification. The features used for comparison include those categorised into four sets as Fourier power spectrum, second order grey level statistics, grey level difference statistics, and grey level run length statistics. The authors compute a total of 64 ....
....of all classes and the second study only the classification of the first three classes. The study used a total of 45 spectral features including mean, standard deviation, and features based on cumulative frequencies. The textural features computed are based on those proposed by Weszka et al.[223]. These features measure factors such as the amount of total variation within the cloud sample and the overall homogeneity of the sample data. A joint probability distribution of the difference in grey levels separated in direction q and distance r can be generated. On the basis of this, four ....

The texture features are the grey level di erence vectors (GLDV) textural features [48, 47] of contrast, entropy, local homogeneity, angular second moment, mean, standard deviation, cluster shade and cluster prominence. The GLDV features were extracted based on the absolute di erence between pairs of gray levels at a distance d = 1 apart at four angles = 0 ; 45 ; 90 ; 135 ....

....analysis. There also existed quite a few review papers in this area. An early review paper, by Weszka et al. compared the texture classi cation performance of Fourier power spectrum, second order gray level statistics (cooccurrence matrix) and rst order statistics of gray level di erences [164]. They tested the three methods on two sets of terrain samples and concluded that Fourier method performed poorly while the other two were comparable. In [99] Ohanian and Dubes compared and evaluated four types of texture representations, namely Markov Random Field representation [39] ....
