Changeset 27697 for trunk/psLib/src/imageops/psImageCovariance.h

Message:

psImageCovarianceSum now sums a single covariance matrix to produce a single value, rather than summing multiple covariance matrices into a single covariance matrix. This is useful when we're not interested in the pixel-to-pixel variation, but in the noise over areas of the scale of the covariance matrix (or larger).
