What are the dynamic flame tracing methods?

Particle filter algorithm. Particle filter algorithm based on weighted color histogram is used to predict the position of flame target, and then multi-class features of dynamic flame are extracted from the tracked candidate areas, and the flame target is judged by multi-feature fusion through multi-expert system classification method. Flame refers to the burning and luminous gasification part of fire. Flame is a state or phenomenon. The burning combustible gas glows and heats up, flashing and rising.
