<p>To identify the boundary pixels of a number of particles in the same field of view, an electrical image of the field of view is formed by a CCD raster scan device. The electrical signal from the CCD device is segmented and is digitized. The signals are processed such that the boundary pixels have non-zero values and are linked to one another. The values of the pixels are stored in a boundary memory (28) addressable by a row signal and column signal. In an addressable index memory (78), a plurality of values are stored with each value being an address to the boundary memory where the pixels having the boundary are located. Finally, a location memory (76) which has the same addressable dimensions as the boundary memory where the pixels having the characteristics of interest are located, addresses to the addressable index memory.</p> |
