Abstract
A method and apparatus for analyzing a picture of an effluent such as a smoke plume or dust cloud to determine the opacity of the effluent. The picture of the effluent is first broken down into pixels. Each pixel corresponding to the effluent is identified and the color of each effluent pixel is analyzed to calculate the opacity of that effluent pixel. An opacity value for the entire effluent is extrapolated based on the opacity values of each effluent pixel.
