On the other hand, data mining techniques have gained popularity as illustrative and pre-
dictive applications of image analysis, and researchers have used the two techniques on blood
cell detection data. The neural network (NN) is one of these techniques, and it has been suc-
cessfully applied in the identification and control of dynamic systems. In 1986, David Rumel-
hart introduced concepts related to the NN when he presented a back-propagation process,
which used many layers throughout the network.
Another technique of data mining is the classification and regression tree (C&R), which is
the most common and powerful technique for classifying data and predicting outcomes in the
decision tree (DT). It can generate understandable rules and handle both continuous and cat-
egorical variables [ 4 ] . The C&R tree algorithm had been popularized by Breiman, Friedman,
Olshen, and Stone in 1984, before Ripley in 1996 [ 5 ] . The popularity of DT techniques is due
to two features: (1) the procedures are relatively straightforward to understand and explain,
and (2) the procedures address a number of data complexities, such as nonlinearly and inter-
actions, that commonly occur in real data [ 4 ].
This chapter is divided into two parts. In the first part, I apply a proposed algorithm to de-
tect benign and distorted blood cells (sickle-cell anemia) and to count them depending on the
segmentation of their shapes using CHT, watershed, and morphological tools. In the second
part, I introduce an algorithm for checking and analyzing the resulting cell data variables (e.g.,
area, convex area, perimeter, and eccentricity) by applying the most important techniques in
data mining, NN and DT (C&R tree), to get the right decision for diagnosis [ 6 ] .
To this end, the chapter is organized as follows: Section 2 focuses on the related work which
is presenting a literature review on the work in this chapter, and Section 3 presents the dein-
ition and features of the Hough transform. Section 4 provides an overview of the NN. Section
5 discusses the C&R of DTs, and the proposed algorithm is presented in Section 6 . In Section
7 , the experimental results show the effectiveness of each model, and I offer a conclusion in
Section 8 .
