In this paper we present a model of geometry of vision which generalizes one due to Petitot, Citti and Sarti. This is equivalent to the existence of a gap in the diameter of orbit spaces of compact connected Lie group unitary actions on the Hermitian spheres. Two key features are strictly related to the use of measures: on one side, this setting permits to generalize both microscopic and macroscopic crowd models. We study sufficient conditions for convergence to consensus and flocking of non-linear multi-agent systems subject to random-in-time communication failures. The control is a vector field, representing a perturbation of the crowd velocity, localized on a fixed control set. I am with the Department of Mathematics "Tullio Levi-Civita"..
