3. RESULTS AND DISCUSSION
Figure 2 a and c are characteristic lobuler type of infiltrating carcinoma ILC and the type of infiltrating Ductal Carcinoma IDC, while b and d is the
excerpts of each ILC and IDC with a size of 5 cm x 5 cm which will be analyzed to make mathematical models.
a b c d Figure 2. a ILC, b Excerpts of ILC with a size of 5 cm x 5 cm. c IDC. d
Excerpts of IDC with size 5 cm x 5 cm. Formulating mathematical models that can classify infiltrating ca mamma,
then do skraning variable physical quantities movies x-ray results of mammography images using the method of logistic regression results as follows.
Optimum variables for classifying types of histology there are Entropy E, angular secound Moment MA, Mean MN, Entropy of Hdiff EH, angular
secound Moment of Hdiff MAH, Mean of Hdiff MHD. With the estimated value as the following equation:
