Chagas Parasite Detection in Blood Images Using AdaBoost

Figure 11

Two representative images. In image (a), the number of dark pixels makes it easy for the detection system to consider it as a valid parasite. In image (b), the number of dark pixels is larger than average, which makes it difficult for the detection system to consider it as a valid parasite. An easy background looks like (c) and a difficult one looks like (d).
