Estimation of Particulate Levels Using Deep Dehazing Network and Temporal Prior

Figure 3

The differences between the estimated haze effects varied by PM concentration level (15 μg/m³ and 37 μg/m³). The estimated haze effect images in RGB channels were converted to grayscale image for a clear comparison.
