◆ computeAverageBandValue()

double ossimU8ImageData::computeAverageBandValue ( ossim_uint32 bandNumber = 0 )

◆ computeMeanSquaredError()

double ossimU8ImageData::computeMeanSquaredError	(	double	meanValue,

virtual

This will call the compute average band value and then use that in the calculation of:

It will then do a SUM[(Mean - Actual)^2]/width*height.

This is the average variance from the passed in mean. Basically think of the mean as a completely grey image and we would like to see how this image varies from the passed in mean.

Will take the normalized input and convert it to this tile's data type. Example: if this tile is of type UCHAR and its input is of type NORALIZED_FLOAT it will unnormalize the data by doing:

minPix + normalizedInput*(maxPix-minPix)

on a per band basis.
