Part-based flame detection device and method

摘要

The present invention relates to a flame detection apparatus and method, and more particularly, to a flame detection apparatus and method that extracts a portion estimated from a flame in an image, and has a characteristic shape of a portion corresponding to a flame in a portion estimated by a flame, The present invention relates to a flame detection apparatus and a flame detection method based on a partial region for determining whether or not a flame is generated using a point. To this end, the partial area-based flame detection method according to the present invention includes the steps of extracting an image patch, which is a part estimated from a flame in an image, extracting feature points from the image patch, Obtaining an image patch similar to a flame by applying a learned classification algorithm to the image patch, removing an image patch having no flame random characteristic from the image patches similar to the flame, applying a space-Calculating a probability for a pixel estimated to be a flame; and detecting a flame if the calculated probability is equal to or greater than a predetermined value.;
