This paper presents a bio-inspired model for visual perception of motion through its principal indicator : the neuromimetic motion indicator (NMI). This indicator emerges out of the mechanism of antagonist interactions (MAI) where an architecture of oriented columns, local and distributed interactions of the neurons in the primary visual cortex (V1) is operated. The NMI indicator classifies the motion in : null motion and motion, and it estimates the number of moving objects in the scene.
