Detailed Description

This implements a Local correlation fusion based on the paper:

"A Local Correlation Approach For the Fusion of Remote Sensing Data With Different Spatial Resolution In Forestry Applications" by J. Hill, C. Diemer, O. Stover, and Th. Udelhoven Published in: International Archives of Photogrammetry and Remote Sensing, Vol 32, Part 7-4-3 W6, Valladolid, Spain, 3-4 June, 1999

A new band is computed by the formula:

ColorHigh = ColorLow + RegressionSlope*(PanHigh-PanLow);

Adjustable paraemters have been added to clamp the regression slope and attenuate colorLowOffset value and blurring the Pan.

ColorHigh = ColorLow + Clamp(RegressionSlope)*Attenuator(PanHigh-PanLow);

The regression coefficient is coputed for each color band.
