Fire Boundary Detection Method Using a Unique Structure from Motion for Non-Rigid Bodies Algorithm (SFM-NRBA)
TL;DR: A unique algorithm known as SFM for non-rigid bodies (SFM-NRB) algorithm is introduced, which calculates a randomness figure of an object boundary to differentiate fire from none fire event and ability to detect the onset of fires in an image by using a combination of simple three step search algorithm and randomness figures of object boundaries even under complex static and dynamic background conditions.
