Models were developed for describing the regular pattern of blue cones in macaque retina. Two functional descriptions were applied to patterns, one based on the cdf of interpoint distances, the other on the cdf of the central angles of Voronoi regions. Disordered triangular and square lattices and hard balls failed to model the blue-cone point pattern. An elastic-ball model was developed whose spatial properties fit well those of the blue-cone pattern. This model employed a hard core and a soft surrounding shell and is proposed as a valid model for the blue-cone pattern. [ABSTRACT FROM AUTHOR] |
