Definition of flux A continuity equation is useful when a flux can be defined. To define flux, first there must be a quantity q which can flow or move, such as mass, energy, electric charge, momentum, number of molecules, etc. Let ρ be the volume density of this quantity, that is, the amount of q per unit volume. The way … See more A continuity equation or transport equation is an equation that describes the transport of some quantity. It is particularly simple and powerful when applied to a conserved quantity, but it can be generalized to … See more In computer vision, optical flow is the pattern of apparent motion of objects in a visual scene. Under the assumption that brightness of the … See more Conservation of energy says that energy cannot be created or destroyed. (See below for the nuances associated with general relativity.)
