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 addressable by a row signal and column signal. In an addressable index memory, 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 has the same addressable dimensions as the boundary memory. The location memory stores, in address locations corresponding to address locations in the boundary memory where the pixels having characteristics of interest are located, addresses to the addressable index memory. |
