Embodiment 1
[0049] see Figure 1-Figure 2 , the present embodiment provides a flame recognition method based on video image brightness, comprising the steps of:
[0050] Step S1, first read the video stream information, and capture a frame of image therein, as the basic information for the implementation of this method. The original information is generally the RGB information of the image, and each channel value of the corresponding pixel point (x, y) is R(x, y), G(x, y), B(x, y) based on this, Through the conversion relationship between the RGB color space and the YCbCr color space, the YCbCr information of the image is obtained, and each channel value of the corresponding pixel point (x, y) is Y(x, y), Cb(x, y), Cr(x , y), for use in subsequent algorithms.
[0051] Specifically, R(x, y), G(x, y), and B(x, y) respectively represent the values of the red, green, and blue components of the pixel at the (x, y) spatial position; Y (x, y), Cb(x, y), and Cr(x, y) represent the difference...
