Image processing and machine learning in the morphological analysis of blood cells.

Area of Science:

• Hematology
• Computational Pathology
• Medical Imaging

Background:

• Peripheral blood smear analysis is crucial for diagnosing hematological malignancies.
• Traditional morphological assessment can be subjective and time-consuming.
• Advancements in image processing and machine learning offer potential for automated cell analysis.

Purpose of the Study:

• To review the application of image processing and machine learning in the morphological characterization and automatic recognition of cell images from peripheral blood smears.
• To focus on the utility of these technologies for identifying malignant lymphoid cells and blast cells.

Main Methods:

• Outlining the fundamental principles of segmentation, quantitative feature extraction, and classification in image analysis.
• Discussing recent literature on automated cell recognition in hematology.
• Highlighting the specific application to malignant lymphoid cells and blast cells, while acknowledging red blood cells' context.

Main Results:

• Image processing and machine learning enable efficient, objective, and rapid morphological analysis of blood cells.
• These technologies can assist cytologists in interpreting complex morphological features.
• Automated systems can serve as valuable learning and survey tools for hematological diagnostics.

Conclusions:

• Image-based automatic recognition systems show significant potential for integration into routine laboratory diagnostics.
• Further research is necessary to optimize these systems and define effective screening strategies.
• Integration with existing methodologies can enhance the overall efficiency and accuracy of blood cell analysis.
