Characterization of blood samples using image processing techniques

This paper presents a methodology to determine human blood types in an emergency situation as well as a reliability study of the methodology proposed. The plate test is employed to determine blood types, allowing the macroscopic results observation. A CCD camera captures an image of the plate test results that will be processed through image processing techniques available in the IMAQ Vision software from National Instruments. The techniques used in this work are able to determine the occurrence of agglutination allowing the determination of blood types with an algorithm of classification. The reliability study based on statistical tests determines the level of confidence of the approach. The equipment developed is able to automatically perform the plate test and determine blood types.
