Method and apparatus for detecting smoke from image

摘要

Provided are a fire detecting apparatus and a method thereof for detecting a fire, the method includes operations of extracting a feature of at least one object in an input image by using a value of a brightness difference between pixels of the input image or by using an RGB value of the input image; converting the extracted feature of the at least one object into an N dimensional feature; and performing Support Vector Machine (SVM) machine learning on the N dimensional feature of the at least one object.

1. A fire detecting apparatus comprising:
at least one processor to implement:
an object feature extracting unit configured to extract a feature of at least one object in an input image;a converting unit configured to convert the extracted feature of the at least one object into an N dimensional feature, where N is a natural number; anda mechanical learning unit configured to perform machine learning on the N dimensional feature of the at least one object, based on coordinate values of the N dimensional feature, to detect a fire and or a smoke, wherein the object feature extracting unit is further configured to obtain a differential image of the input image, calculate a weight and a differential direction for each pixel of the differential image, generate a normalization image by normalizing a histogram of the differential direction with respect to the weight, and extract the feature of the at least one object from the normalized histogram.
