Furthermore, as the texture information contributed to the classification performance (Weng, 2012), the local textural measures based on the gray-level co-occurrence matrix (GLCM) were adopted; however, because of the redundancy and similarity between texture features (Rodriguez-Galiano et al., 2012), only the variance, dissimilarity and ... GLCM dissimilarity sum of all directions from NIR. Furthermore, the second-order textural parameters based on GLCM added no information in order to improve the classification accuracy.Jul 29, 2016 · Other than GLCM mean of maximal correlation coefficient at 32 quantization level, all features have favored conditions with a Q measure of less than one, as shown in Tables IV and V. In general, quantization level of 25 and 32 did not have much impact on the way the GLCM features behave.

These radiomics parameters including higher GLCM-entropy and -dissimilarity and lower GLCM-correlations were strictly associated with a worse prognosis.Next, two features of the GLCM matrices are computed: dissimilarity and correlation. These are plotted to illustrate that the classes form clusters in feature space. In a typical classification problem, the final step (not included in this example) would be to train a classifier, such as logistic regression, to label image patches from new images.
