5. CONCLUSIONS<br />

From the results it follows that the descriptors used in the literature are highly objective and<br />

functional, this paper makes a valuable contribution to the CASA systems, proposing MSM1<br />

MSM2, MSM3 and TCF descriptors, increasing the percentage of effectiveness in<br />

classification. Future work will include another set of descriptors that help increase efficiency<br />

in the analysis and classification of motility also will be implemented as classification and<br />

clustering using geometric descriptors.<br />
