Abstract
A rapid succession of objects such as sweets are sorted according to shape by being fed through a viewing zone, flash illuminated in the viewing zone, and viewed by a number of fixed electronic viewers spaced in one plane around the viewing zone through just under 180.degree., the edges of the images produced by the viewers being examined for approximation to a spherical shape, approximation to symmetry and reentrants, and one of a number of air jet nozzles being thereby automatically energised to direct the object into an appropriate bin.
