specific Embodiment approach
[0025] Specific implementation methods: such as figure 1 As shown, the image-based air quality level assessment method described in this embodiment includes the following steps:
[0026] Step 1. Since there is no public image library for the research on image-based assessment of air quality levels, we selected 100 images with air quality level labels and related pollutant information from the Internet, and used these images as the model building Air Quality Image Library.
[0027] Step 2. Since the HSI space is more in line with the visual characteristics of the human eye, and its component correlation is much smaller than that of the RGB space, we first transfer the images in the air quality image library from the RGB space to the HSI space. The conversion formula is as follows:
[0028]
[0029]
[0030]
[0031]
[0032] Then the images of different air quality levels are explored and analyzed in the HSI space.
[0033] Step 3. From step 2, we can see that in ...
