Embodiment Construction
[0048] The detailed process of the inventive method will be clearly and completely described below with reference to the accompanying drawings and embodiments of the description.
[0049] The present invention provides a black smoke vehicle detection method based on multi-scale block LBP and hidden Markov model, and its flow chart is as follows: figure 1 shown, follow the steps below:
[0050] Step 1: Detect moving objects and determine key areas from surveillance video;
[0051] Step 2: Extract multi-scale block LBP features to increase scale and location information;
[0052] Step 3: Use the Hidden Markov Model to describe the dynamic features of the key area, and divide the current frame into a black smoke frame and a non-smoky frame;
[0053] Step 4: Through the analysis of the video sequence, combined with the distribution characteristics of the black smoke frame, further identify the black smoke vehicle.
[0054] The method for detecting the moving target in the step ...
