Real-time air quality estimation based on color image processing

This paper address the problem of efficient, realtime estimation of the particulate mass concentration, exactly PM2.5 (particles with aerodynamic diameters less than 2.5 μm) from a superb view image. And the proposed method is to achieve high degree of accuracy at the cost of only modest user's effort by analyzing the relationship between the PM2.5 and the degradation of the observed image. With the fitting algorithm with experimental data, the PM2.5 could be real-time estimated by a general camera with little artificial participation, and the correlation coefficient produced by our data set and the standard observation will be as high as 0.8219, as the MSE (Mean Squared Error) value 51.2324 μg/m3.
