A first paramater is measured for each of the plurality of different particles. One of the type of particles (A) is identified based upon the first parameter measured. Once the one type of particle is identified, a second parameter, different from the first parameter, is then measured for the one type of particle. The other types of particles (B) in the field of view can be identified based upon the second parameter associated with the one type of particle which has been identified. In one example, color is first used to differentiate various different particles in the field of view and to identify one particular type of particle. Thereafter, a morphological parameter, such as size, associated with the one type of particle identified is measured. The measured morphological character associated with the one type of particle identified is used as a threshold to differentiate other particles in the field of view based upon the second morphological parameter. Similarly, a morphological characteristic can first be used to differentiate one type of particle. A second spectral parameter, such as color, can be measured for the one type of identified particle and can be used to differentiate other particles. |
