This paper investigates a pattern recognition framework in order to determine and classify breast cancer
cases. Initially,atwo-classse paration study classifying normal and abnormal(cancerous)breast tissues
is achieved.The Histogram of Oriented Gradients(HOG),Dense Scale Invariant Feature Transform
(DSIFT), and Local Configuration Pattern(LCP)methods are used to extract the rotation-andscale-
invariant features for all tissue patches.A classification is made utilizing Support Vector Machine(SVM),
k-Nearest Neighborhood(k-NN),Decision Tree,and Fisher Linear Discriminant Analysis(FLDA) via
10-fold cross validation.Then,athree-classstudy (normal,benign,and malignant cancerouscases)is
carried out using similar procedures in a two-classcase;however,the attained classification accuracies
are not sufficiently satisfied. Therefore,a new feature extraction framework is proposed.The feature
vectors are again extracted with this new framework,and more satisfactory results are obtained.
Our new framework achieved a remarkable increase in recognition performance for the three-
class study.
