def bccResultComputation(sampledRGB, filterRadius, exposedTime, airFlowRate, bcGradient, gradient, chartFile, parenttags=None, level=logging.ERROR):
''' This method gets invoked externally with the specified params and computes the BCVol,
it also plots the chart.
Keyword Arguments:
sampledRGB -- The sampled RGB values of the BCFilter
filterRadius -- The radius of the filter in the image
exposedTime -- The time duration for which the filter was exposed.
airFlowRate -- The flowrate of the pump
bcGradient -- The gradient values to be used in the interpolation to ind the BCVol
gradient -- The gradient/grayscale list that is used in the interpolation
chartFile -- The name of the chartFile in which to store the plotted results
parenttags -- The tag string of the calling function
level -- The logging level
Returns:
BCCResult object containing the results of the Image Analysis.
