A programmatically described solution to the segmentation problem is taken as opportunity to dicuss the neural architecture problem of vision. At the center of this problem is the formation of holistic entities (the Gestalt phenomenon) out of masses of neurons (the binding problem). As formulated in the Dynamic Net Architecture (DNA), neurons can become part of a (short-term) stable state only if supported inside a coherent network ('net'). Integration into nets is the basis for global treatment of structures, such as recognition as rigid body or projection to an invariant model.
