The Acousto-Optical Method for Blood Typing (Part 1). Photometric and Statistical Methods for Image Processing

Abstract

This work is devoted to the analysis of two possible ways of computer processing of photographic images used in acousto-optical human blood typing. Such analysis is necessary to solve the problem of increasing the time resolution and, as a result, the reliability of blood typing by the acousto-optical method. The results obtained using the suggested statistical approach to image processing are compared with the results obtained using the conventional photometric approach. It is shown that the statistical processing of photographic images provides a 1.5- to 4- fold gain in the resolution of the acousto-optical method in the case of forward typing. For reverse typing, a 2- to 5- fold gain is achieved. This work can be considered as a step towards further improvement of the acousto-optical instrumental method for blood typing.
