发明名称 Method and apparatus for digital analysis of multiple component visible fields
摘要 A means and method for digitally analyzing multiple-component fields measures the relative proportional content of each component in the field. A selected field area is recorded to create a record which may be divided into a plurality of discrete segments each of which has an identifiable intensity, such as an ascertainable visible intensity. The visible intensity of each discrete segment is digitally resolved into one of a preselected multiple of discrete gray-level values, the frequency of which may then be registered to obtain a frequency distribution, such as a histogram. The frequency distribution is resolved, such as through a Gaussian mixture analysis, to approximate the observed data by multiple, normally distributed component distributions. Each of the component distributions is then representative of a selected component of the field, thereby providing a measure of the proportional content of the field area which is comprised by each component. Additional embodiments simplify the analysis of the multiple-component field by initially identifying a visible intensity typically associated with each component and subsequently analyzing the frequency of occurrence of that particular visible intensity among the digitally resolved field segments.
