In the present embodiment, video sequence pretreatment is carried out before step 31 is performed, in addition to video to be detected.Video
Sequence pretreatment is by sport foreground separation and color analysis, first to quiet under motion video image and same camera lens
State background is contrasted, and draws the track that moving target moves during camera is shot;Then color is carried out to moving target
Analysis and Gaussian smoothing filter, obtain preliminary smog suspected target region.Comprise the following steps that:
1) sport foreground separates
Sport foreground separation using independent component analysis (Independent ComponentAnalysis, ICA) technology and
Vision significance (Graph-BasedVisual Saliency, GBVS) based on figure carries out smoke foreground separation.Sport foreground
Separation first uses improved ICA moving objects identification model initial gross separation smoke foreground region in smog separation phase, then passes through
GBVS determines smoke foreground marking area.
2) color analysis
At the initial stage that fire occurs, because temperature is than relatively low, object often burns not enough fully, can produce linen cigarette
Mist.Smog itself is translucent, and for smog often than sparse, this can cause background image to fog during just generation;With
Smoke density increase, background image all cover from translucent to by smog, and background image loses original color characteristic, institute
So that smog can be judged whether according to color characteristic.
Under RGB color model, the gray value of tri- components of R, G, B of smog is fairly close, so if meet simultaneously
Following two conditions, then it is assumed that the pixel meets the color characteristic of smog:
Condition 1:Still equal, i.e. h three components of RGB color model increase and decrease simultaneously afterR± a=hG± a=hB± a, its
In, hRRepresent the gray value of R component, hGRepresent the gray value of G components, hBThe gray value of B component is represented, a represents constant;
Condition 2:It is the I component satisfaction of HSI models after HSI color models by RGB color model conversation:L1≤I≤L2 or
Person H1≤I≤H2, wherein, I represents that intensity or brightness, L1, L2, H1, H2 are component I empirical value.
After carrying out above-mentioned video sequence pretreatment, pretreated video to be detected is obtained, Smoke Detection can be reduced
Amount of calculation, improve detection speed and detection efficiency.
In the present embodiment, step 33 specifically includes:
