Best Machine learning algorithm to detect fire in OpenCV -

i need code fire detector using opencv , ive been googling days on use failed. find in google haar detecting rigid objects face best ml detect fire? have use ml algorithm, means no haar or viola algorithms.

any suggestions this? , if possible can explain why algorithm applicable in detecting fire

better if consider machine vision problem rather computer vision problem. instead of using rgb camera, better go rgb-ir camera.

infrared cameras sensitive heat content in scene. when use ir camerasm simple algorithms or mere thresholding can detect fire in scene in case of dark environment.

cheap rgb-ir cameras available online raspberry pi's pi-noir camera or can convert camera rgb-ir camera removing ir protection film.
